It's tough to prevent these things. It's like trying to swim in a giant strainer and not sink. If you plug one hole, there are a million others, and who knows how many more.
Just tonight, I've deleted about 90 phony accounts from the system, added a handful of new ban rules, and added a few more domains to the list of email providers you can't sign up with. The "no Gmail" rule that unfortunately frustrates a number of legitimate users prevents on a daily basis dozens of phony account signups.
Thanks to those who take the time to point out suspected phony accounts or alert me to spam posts.
