They might be alts, which according to the forum rules is allowed. So, I don't think any DT member may tag the accounts on grounds that they are just alt accounts posting in gambling section or exchanging merits {at least in the past, accounts engaged in merit abuse have not been tagged}
Once upon a time I would tag accounts if I knew they were alts and I saw them having bizarre conversations with each other in the same thread, which I considered egregious spamming....and then the merit system came along, my blood pressure went down, and I'd no longer engage in that kind of tagging. So yeah, I agree that if a bunch of accounts appear to be the same person but aren't enrolled in the same bounty/campaign, it's not an issue for DT members to take care of, as annoying as it might be.
OP, it's more likely that your account is an alt too. We know it's almost impracticable for a newbie account to know how to hunt down alts when they haven't even got used to navigating the forum. With just seven posts to your credit you're already acting detective.
Heh heh, well there's that too. On the other hand, this isn't the first time I've seen new accounts kick off their bitcointalk career by trying to bust scammers. That doesn't really raise any red flags IMO.
What you need to think about is the issue of the 4 high ranking accounts I've mentioned in this thread as most of you seem to only care about newbie scammers for shitt-token and worthless altcoin.
The problem is that there isn't anything for DT members to do unless there's solid proof that those four accounts have broken a forum or bounty rule or committed some kind of tag-worthy infraction. The evidence has to be solid enough to withstand scrutiny by the community for having been given by a DT member, because any DT member who hands out too many wrong feedbacks is going to get booted off the DT list eventually.
