Today I took a deep breath and started to check today's new topics on the Bitcoin Discussion thread.
Today our hard working little newbie ants has created 10 pages of new topics (roughly) and I took my time to check those topics which had less then 10 posts... it took an hour or more (even more...).
The result is 127 reports but the reason I'm amazed/frightened is:
90% of the posts was done by a newbie with 1-2 activity points or a brand new user....
The naming concept of the newbie was like this: Firstname+numbers, like Annie456 and so on... and they were different users, of course....
Most of the topic opener posts were about bitcoin price speculation, in max. 2-3 lines...
I still have a few (OK a lot) tabs open in my browser, for the post that were longer than 2-3 lines because I'll do a copypaste check on them, but it's possible that it will be the job of tomorrow

I hope the mods won't get headache from the amount of report I've generated for them

Most are plagiarism. What they benefit from doing this I don't exactly know, but I've found several threads made by these 1 post newbies which are either completely copy, and pasting or are only using a snippet of the text from another source. They seem to be getting a lot of it from news websites, but are also copying from much earlier posts on this forum too.
Seems like the person behind the bot likes to add a few emotes in it too. They seem to be targeting older posts that were made by substantial users, although they have just copied posts from earlier today too. They also like adding punctuation marks such as "!!!".
