They've gotten smart too. They post their spam links then use their other account to quote them so if the original is banned and deleted it doesn't get deleted because quoted posts are not impacted. Also, they like to post and then a year later come back and modify the post adding in the spam link. Use their other account to quote the year ago post and bam, spam links brought right to the top and undeleteable.
They sneky. I haven't bothered to look where they go but hopefully not ransomware sites. That would suck for the...less intelligent posters we have around here.
