World of Warcraft is turning like the rest of the internet, full of Boosting messages in chat, whispers, LFG tool, etc. As Blizzard is not doing anything about it, let's filter the clutter ourselves!

Current features:

Automatically block messages sent more than once from the same user within defined timeframe (default 5 min) in Say/Yell/Whisper and all official WoW channels (General, Trade, LocalDefense, WorldDefense, LookingForGroup, GuildRecruitment)
Adblock aka Proactive mode: Aggressively blocks obvious boosting messages from the first occurence
Blacklist users to be permanently filtered out of your chat
Whitelist users to always be allowed (automatically done for friends and guildies)
Audit mode: Try out AdBlock to see what it would block without actually blocking anything
Autoblock mode: adds to the permanent blocklist repeating offenders
Show how many messages were blocked this session/overall
Block history: Show the last blocked message by AdBlock (default to last 50)

GUI

Recommended usage

type "adblock:test" in the /s and make sure the adon works
Type /ab and start fine-tuning the AdBlock to your taste
Start in Audit to make sure it would not block messages you would like to keep
If you're a bit scared of blocking important stuff:
Activate "Audit" mode to make sure it would not block messages you would like to keep
Later, remove Audit and switch to Verbose to see when messages are being blocked
You can see blocked messages history at any time in the settings of via /ab history show
Finally, you can activate Auto-Blacklist to permanently mute players that repeatedly trigger Adblock

Planned features:

Translation of other locales
Some assisted mechanism to report biggest spammers
A surprise to try keeping spammers at bay ;)

How can I help?

Make translation for the other locales! It's very simple and does not require any coding skills. All you need to do is:
Download the file https://github.com/Astorsoft/Adblock/blob/master/Locales/enUS.lua, make a copie of it and rename it with your own locale (see the list below) for example name your copie deDE.lua for German.
Open the document with any editor of your choice, Notepad is perfectly fine
Each entry to translate looks like this: L["My text"] = true
Just replace the word "true" by the translation in quotation marks
For example if I would translate the above line in French it would be L["My text"] = "Mon texte"
Make sure you follow the case, spacing and punctuation of the original text
You can then either make a "pull request" on github, or, if you have no idea what the heck is a pull request, just PM me the result over CurseForge and I'll credit you for the translation :)

Current localization status:

"frFR": French (France) - Done
"deDE": German (Germany)
"enUS": English (America) - Done
"itIT": Italian (Italy)
"koKR": Korean (Korea)
"zhCN": Chinese (China) (simplified)
"zhTW": Chinese (Taiwan) (traditional)
"ruRU": Russian (Russia) - Done, thanks to LordRomzessV!
"esES": Spanish (Spain)
"esMX": Spanish (Mexico)
"ptBR": Portuguese (Brazil)

Known bugs:

FIXED in 1.1: Keyword with accents or non-latin characters are now supported if the user untick the "Advanced filtering" option in the "Ad-Blocking Keywords" option panel
FIXED in 0.9: AdBlock is not playing well with Elvui's chat history for some reason
FIXED in 0.9: AdBlock is not handling multiple chatframes

FAQ

Can't you also block Boosting ads in the LFG tool?: I wish I could, but blizzard does not allow addon to analyze group names and comment in the LFG tool... Please take the time to report them in-game as Blizzard do ban those guys! (source: https://www.wowhead.com/news=317125/one-day-ban-for-advertising-in-group-finder)
