I need more information than that to be able to debug the problem..
like the actual email names and the accounts that they tried to open.
One heuristic that has been tripping up people is where they have a
large set of numbers in their accountname. The spammers use bots which
put long streams of numbers in their account names as in
<zue<randomishnumber>> <zue<randomnishnumber+X>>. This allowed them to
know which spam farm and ad campaign they are going to use as all of
zue<> get Printers while anil<> get Pills and greg<> might get
Antivirus tech support. So our heuristics were looking for accounts
with long numbers as a higher score. However this breaks down for
some countries where the numbers may mean something or are required
because bob8888 is chosen a lot so bob88881001 bob88881002 would be
given out. We can work on this but we will need some data on who they
Please extend our apologies and thank them for their patience.
