Prevent users with hotmail account from logging in

Hi Guys!

My website is slowly being destroyed by spammers joining in my site and all of them uses @hotmail.com account. Is there anyway I could prevent everyone using @hotmail.account from ever joining in?

Thanks,

Sam 

Search the forums; there is/are topic(s) on this posted.  There are also modules in the market but it has been discussed in the forum.  Use an external search engine searching on say, "Boonex block email accounts" or some such query string or use the search engine's advance search and search on the boonex.com domain.

 thanks geeky girl!

As geek_girl mentioned. There are many topic posts to help fight spam.

My anti spam available in the market is able to detect and stop bots, and even block email addresses you don't want as well as other things. A very good option for those that do not want to make modifications to the site.
