Thanks for the feedback, Ive been a little slack over the last week in keeping up the date with the thread but I do have a bit of good news
gmail.com - I hate it. I hate it because they normalise all the email addresses. It removes all the .'s and ignores everything to the right of a + in an email address
spammer
joeblogs@gmail.com registers and uses
joe...b.l.o.g.s@gmail.com or
joe.blogs+spam@gmail.com and it all gets delivered to the same account but this throws the api as it did a like for like comparison... until now
I spent the last week running tests on a new code and database revisions on the stopforumspam.com website
So now if
joe...blogs+aaakslsl@gmail.com registers on your forum and
joe..blogs+ss11.......1.1.1.1@gmail.com has been listed as a spammer, youll get a positive hit and the registration will be denied.
