because thare are a lot of proxy sites which allow users to change their IP-s.
Ուտոպիստ, many user have dinamic ip address and they are changing every minute and it can be changed manually. And there is many softwares that is doing the same job. So ip blocking is not helping
I am comlleetly agree with you, but
From this IP 188.8.131.52 adress someone spamed my site. he has registered about 80 times using different names, E-mails. My suggestion will prevent this cases. and will make this kind of spammers work harder and harder.
It would be great if we could select also the countries, from which we want people to be registered in our sites.
E-mail domain selecting will filter too, because E-mail Verification overcoming will be much more harder for spamers with several mail services (for example with gmail, or yahoo mail services). Because Spaming us they spam also these E-mail servers! And so we can "use" Google mail security guard for protecting our registration bases.
