You say "Delette Spammer" is equivalent to "Delette with content", do you mean that the data is also transferred to STP and controlled at registration as in Dolphin? If so, is it a good point that I did not know, you confirm that it works the same way?

What is S.T.P ?

No it doesn't happen in UNA, also in Dolphin data is submitted to StopForumSpam only if you apply for special key which allows to do it.
