Friends disappearing?

I've noticed that some of my friends that are new and just created an account are dissappearing. I mean I can't find them anymore. All of their questions that I responded to are gone. All of the comments that they sent me are gone. Their profile is...

gone. I mean I have had a couple of friends who just joined and now they are missing? Where did they go. We were talking and the next minute all history of them dissappears. Does anybody know?

Some of them may have deleted their accounts - then all their account info dissapears and their questions and answers I believe are turned into funadvice (or could be fau, I always get the two mixed up)
Some of them may have been deleted by the admins for breaking a rule, same thing happens to their questions and answers...

Ah - well, a few issues:
1) Same IP address as you have
2) Location was other side of the country, so it means the location was modified
3) Inflamatory comments on religious issues - which we don't allow per our terms of use.

If they want to register, have them use their own computer...so we don't get suspicous delete their account on the grounds that it's duplicative of an existing member.

And for stuff like this, have them contact us via the contact link in the footer - because, if I had my account deleted, I'd ask personally...you asking makes me even more suspicious that you were behind both accounts, rather than the other one belonging to a friend of yours.

Thanks!
