Re: Getting junk mails after registration...
It may happen. There are automated bots out there that are designed to skim email addresses from forums like these.
The easiest solution is to simply make the email invisible. That's quite trivial to do. You can put the address on a 'vCard' that has to be downloaded but that isn't directly viewable from the site and would require another step in the bot's procedure.
I've never had a problem with spam on here. With my current email address or the addresses I've used since 2004.
