I've already mentioned this at least once. Imagine a crime where 3 entities are involved, and only 1 always gets punished for it. That's what has been going on BTCT for a while (albeit even less effectively in 2016). What should be done is, punish everyone involved:
1) Ban the spammers themselves.
2) Ban the managers.
3) Ban the service.
If the service
does not care about the spam, then it should not be allowed any kind of back-linking from BTCT period.
Easiest way is to disable all signatures for all users and that will repel 99% of the signature spammers.
That's the last and most drastic solution to this problem.
No. That project never took off (i.e. has failed) and even some of those managers are inadequate (e.g. yahoo62278).
