Bein-Hasdorim;I know (exactly) what you mean. On another (Heimishe) blog, I used another (posting) name, (which BTW this blog disallowed for the reason that “It’s taken already”. Actually by me, with another e-mail address, but I’ve forgotten the password.) which I (purposely) spell different than the standard way. (With Three EEEs (Like bigwheeel, for example.) One day, I noticed comments which would be impossible to have been posted by me due to their spoof nature and time posted (Because I’m on the road transporting Yeshiva kids at that time.). And those (spoof) postings were spelled the standard way.(bigwheel). that is how it slipped past the editors, even though the imitator has a different IP address. After I contacted the editor, they promised to be more vigilant. And the “Copycats” stopped showing up.
p.s: Whoever understood my ramblings is a genius.
