Use the signed message is a ridiculus way, a person may never have had it (lost or delete it), but is not the problem.
Registration email is a lot safe way. The feedback of a member of staff (a staff member not a dog) is a good way too.

I give up. I'm out from this world since 2016, just piss me off wake up a day and see that scammed people denounced me.

Run a forum is not a game. Privacy and security are serious things. Have no support (or adeguated protection) is not an excuse.


Thanks all. Goodbye
