Re: If this contiunes, we'll lose the Bitcoin Discussion topic
I wonder, who has been reporting a lot on altcoin section? those boards need more than 3 active moderators. I'd suggest people to start reporting more in altcoin section.
Why not you give it a headstart? You have told members before to report 200 posts and other nonsense in the name of the helping the forum, why don't you do the same. You might get your negative removed, like you said in your trust ratings given to others. 
My question to the mods, how to properly report those threads?
"This user might be a bot since there are others with the same nickname style that are posting crap" does't look like a good explanation to me in a report.
Like Welsh said, just report it as plagiarism if that's the case. If the bot is posting random stuff in random threads, report it as off topic / possible bot. Different mods have different understandings, so your reports might be marked bad if enough evidence is not available, though that will be a rare case. "This user might be a bot since there are others with the same nickname style that are posting crap" does't look like a good explanation to me in a report.
