I get a lot of Xrumer Bots (like the above user "
DRESS"?) attempting to registering with Yahoo, but by far their favourite email account seems to be GMail, but I would never add it to the banned list (even if it included lots of dots:
I.could.be.legit.bla@gmail.com)
Why, there are so many other ways of stopping bots, why cause any potential negative impact on your users
The first two lists of temporary email accounts I would ban, but I would never add something like *.*.*.*@gmail*/ *.*.*.*@hotmail*/ *.*.*.*@yahoo* to a banned list, or even *.*.*. * . There are better ways to stop spammers that don't have a negative impact on legit users
Recent Xrumers favourites, example (these are all definitely bots, since they complete hidden fields that users cant see):
