Hmm, a couple of things to note..

Firstly.. that filter would likely achieve what you want, but I wouldn't personally add it without having a stronger match. There's a very unlikely chance you could catch someone you do not intend (for example someone could say F*K THESE GOLD SPAMMERS IF ONLY THE DEVS WOULD DO SOMETHING!" and you would catch them in your filter.) Unlikely, but possible.

Secondly.. there was a change to the add-on recently where it now tracks spammers and strips all future chat from them for the duration of your session (or until you reloadui.). You can think of this as a client-side only, temporary 'ignore'.) Thus, once the spammer is caught be a pattern they will remain blocked blocked until you relog/reloadui. I saw it as well, what you're describing, which is why I made this change.

Third.. I've done one step better on the pattern config, now when you reset to defaults any customized patterns are retained, new patterns are added and any patterns I've personally changed will be updated correctly. I've also consolidated patterns into a single list. The UI could use some polish since it's a total pain to edit them there, but it works. This change will appear in v1.9, you will want to copy/paste your patterns one last time, of course (all existing patterns WILL be lost when you upgrade to v1.9, so copy them out before you update!)

Enjoy!

Before you update to v1.9 if you have updated your patterns you MUST save them before updating or they will be lost. This version changes the Settings UI. Additionally, this new version should 'merge' new patterns into the pattern list from this point forward, what this means is that with every release you can "reset to defaults" in the Settings UI to pick up any NEW patterns, and also keep any patterns you have customized/added yourself.

Aside from that, there are many bug fixes in this release, including a few new patterns from the last round of spammers.

Most notable change is that if you enable Notifications you can now right-click on the spammer name and choose 'report' (and even ignore, if you so desire.) As before I've taken the stance that I do not want to automate ignores, but, some users feel strongly about reporting these players. I may reach out to the FastReport author in a future version to facilitate reporting spammers (as an option, and still requiring your consent/interaction to do so.)

That said:

v1.9
- Refactor of Patterns into a single list, implemented pattern merge (no longer lose your customized patterns when resetting to defaults, but still get NEW patterns added to Add-On.)
- Reworked Flood/Spam notifications so that the spammer names are links, you can now right-click to report spammers (if you wish.)
- Reworked Flood/Spam notifications so they are shown regardless of which Chat Add-On you are using, this option is still disabled by default.
- Refactored "Spammer Guild Invite" - previous version was notifying, but not actually declining the invites. Was not yet able to test.
- Updated spam definitions, and added a few additional mappings to charmap. Fixed a bug with charmap code not mapping certain characters correctly.
- Misc output window clean-up/colorization, only really matters for people who enable the output options.

After updating to 1.9 you must go into the Settings UI (ESC->Settings->X4D AntiSpam) and then click "Defaults" to reset to default settings. This will cause the spam patterns to initialize.

Immediately after you update there will be no patterns loaded, this is a by-product of the pattern UI and SavedVars being re-implemented.

As a general rule, whenever you update you should go to the settings UI and reset to defaults to update to the latest patterns (unless you don't want to for whatever reason, but at this point it's just a good idea to do it every time.)

Let me know if you still have problems, who knows, maybe something strange is going on...

As of v1.11 LibAntiSpam will perform this sort of update automatically, users will no longer have to reset addon settings to pick up new patterns.

I've added a new spam definition for spammers trying to do ASCII art (quite unsuccessfully.)

Spammers are trying to get creative again, I can think of one more method of bypassing the current implementation but I'm obviously not going to share. Once they figure it out it'll take about 15 minutes to implement a fix. Busy working on another Add-On right now.

Enjoy.

Correct, LibAntiSpam will function without any other Add-On installed and does not actually use any other spam or chat library to do its job. It is also designed to be used as a library by other add-on developers, but to my knowledge nobody else has integrated with it yet. I have a Chat Mod (called X4D Chat) which uses LibAntiSpam as a library, but it's not necessary to use them together for it to work. They are both designed to be used independently, but they will also work together. Hopefully other Chat Mod and Mail Mod developers will adopt LibAntiSpam as a 'de facto' library to help analyze, detect and block spam (without necessarily having to worry about implementing anti-spam algorithms, patterns, etc.)

Thanks for the compliments, my goal is to create a spam add-on that will eventually not require a lot of time to maintain. The definition of new spam patterns is still a little painful, but I do plan on simplifying the process of defining them (so that end-users can enter a domain, like "spammerfoo.com" and have the add-on create an appropriate pattern for them.) Further, I would like to see the add-on sync over trusted channels (such as Guild chat, or perhaps via mail between friend-listed players) to help propagate new pattern definitions. I don't believe Add-Ons have a method of talking to one another, yet, and I really hope ZeniMax changes their stance on this for legitimate/trustworthy add-on developers.

Well, seems one of the more aggressive spammers finally figured it out. Luckily I've had a few days to think about the problem before they did. Thus, v1.13 has been uploaded. This will put an end to 'most' line-break and multi-line spammers without really requiring us to change definitions.

v1.13
- New Algo for Line-Break Spammers.
- New Algo for Multi-Line Spammers.
- Boot in the Mouth for all Spammers.

Enjoy.

v1.14
- Modifications to text scrubbers (leaner scans, more efficient)
- Spammer notification now only occurs once per spammer, rather than for every message detected.
- Spammer notifications are again enabled by default to promote reporting by users.
- Fixed a bug with SavedVars being reset for every release, what a horrible API.

My apologies to anyone that had custom patterns, the last 2-3 releases wiped them out. This was due to a misunderstanding of the SavedVars API (it does not do differencing, it simply wipes any existing vars for every new version of an Add-On, which is probably why Add-On authors don't actually use the Version parameter.)

Enjoy.
