It's been going on for months on the WoC Forums where hundreds of advert-spamming bots just appear on the forums to dig around so they could disturb and spam on old abandoned forum posts constantly.
These bots seem to have an AI that tries their best to sound like a person and make their beginning sentences related to the topic (their "best" isn't that good in most cases), then immediately after their first sentence they insert a random advert spam link that could range in topics from game scams, to in-game currency scams, to college scams, to jewelry scams, to furniture scams, etc.
There seems to be around a hundred of these bot accounts, they seem to have reached almost every post and thread on the WoC Forums, and they constantly post scams on said threads.
I haven't had a good check on the conditions of the WoC Forums in months, but all you need to do is look at the "Happy Earth Day!" thread: https://woc.solverlabs.com/content/happy-earth-day
on the forums to understand how these bots are as all 120 comments (3 pages full) on it are bot accounts.
Hi, unfortunately there are a lot of spammers on the WOC forum, and a small number of people - so we don’t delete it all and leave it that way. Have a nice day!
