Whenever I get a post to my gallery or see a forum post that looks like spam I always report the post as spam, but in addition I then check the user account too. If the user account also smacks of a spam account I report that as spam too (the account being created the same day as the spam post is a good, or should I say bad, sign. The spam posts and accounts I've reported do seem to get removed quite quickly)

Perhaps Renderosity needs some sort of 'good behaviour' period before allowing any newly created account to add any links of any sort anywhere ? Good behaviour could be as simple as not posting any comment that gets reported as (and confirmed by a mod/admin as being) spam. 

But it looks to me as if the bots are already pre-empting that idea. I got two new followers yesterday. Both are new user accounts created yesterday. Neither has posted any spam comment to my gallery. Both have a user icon that looks like a (fake?) company logo. Both have a link to what looks like a (fake?) company website - no way I'm going to click those links! Neither 'company' has anything to do with what Renderosity does (one pretends to be medical, the other cybersecurity). Both are apparently following 9 people. One has included three social links. I was going to report both as spam accounts because I'm fairly sure that's what they are... but neither has (yet) posted any spam to my gallery so I haven't reported them. Yet.
