@Fellmoon We do, but it's challenging to find an exit node that still works as spammers try to abuse Tor for signing up as well... Apologies for the inconvenience.
Thanks for the answer, I guess one just needs to be more stubborn here than I have been ;-)
Do you use captchas to prevent automated signup?
Likewise requesting a donation coupled with an written resquest might help.
Otherwise a invite-only system, where a person can get an account only by invite from someone with an existing account, might work well. If the invited user spams then both accounts are frozen, the #spammer and the inviter.
