Since you use ODBC and ejabberd, I also like to point out EJAB-1031 [1].
This is a bug that causes ejabberdctl to delete accounts based on
usage-information from the mnesia database, even if you use mod_last_odbc.

This was also my major consideration. Also consider that soon all "good"
usernames are taken. Try getting <yourname>@gmail.com for example. I did
a little investigation and gmail definitely does not allow
reregistration, on yahoo mail I found conflicting information, but they
seem to at least block usernames for some time.

At least ejabberd offers a command for this. If some data remains I (and
I am sure Badlop to) would consider this a bug.
