Make a secure email.
Go into your usercp and change your email to that one.
The friendship request emails are automatically generated by the site 'bot and no actual members can ever see them- it's in preferences, too- you can turn off the 'allow email notification' features wherever you find them. I think the 'bot sends friendship requests, infraction messages, and PM notifications and you can turn all of those off and have them only appear when you log on. If you are still having problems, email me or post back up and I'll go poke around and see what else I can do about it.
