I don't agree.
See only suggestions but no arguments.
1) What for verify email?
2) Don't understand that. What you mean with unknown emails?
3) Many use VPN. So what should it bring?
4) Makes sense, but how to realize without immence effort and without slowing down the whole forum?
See only suggestions but no arguments.
its because the thread is intended mainly for suggestions and not on discussions/arguments.
1) What for verify email?
admin must need to implement this feauture when signing up a new account in order to avoid such spam and for account farmers to have a hard time.
2) Don't understand that. What you mean with unknown emails?
unkown emails are not trusted or spam mails/disposable mails.
3) Many use VPN. So what should it bring?
vpn can do amazing things like changing your ip and location and many users find it cool to use. plus it can help them acces bitcointalk if they live in a restricted areas or thier ip has been block.
4) Makes sense, but how to realize without immence effort and without slowing down the whole forum?
no, it wont affect or slows down the forum because these are just basic feautures and wont consume much of bandwith.
