Over the past few days I had a few spam accounts register on my site http://www.photoguides.net
The spam problem's been fixed, got capthca in place and a few other things and registrations have stopped. I'm left however with a few hundred spam accounts that I'd like to get rid of.
They are mainly under three domains, tom.com, 163.com and qq.com
How do I go about deleting accounts with these email addresses in bulk?
Unfortunately when I search for these domains in the users section nothing comes up.
What's the best way to get rid of registration accounts under this domain?
