Check your forums for this user.

So I had a rather odd username, martin1234php, sign up. I checked the profile, and naturally not a single one of the profile fields is filled in correctly, and it's a gmail account.

So I Googled it, and there's ten pages of his username on forums all over the place.

59.92.141.36 is the IP he signed up to my site with. Either a really bad spammer, or a bot looking to harvest email addresses.

Just a heads up.

Edit: Also, I'm assuming that "Asia Pacific Network Information Centre" is an overseas proxy, because I'd say a good 50% of the nonsense accounts that sign up on my site resolve to that IP if I throw it at the lookup tool at www.arin.net.
