Why all of my threads get deleted in Buy/Sell/Trade???

they still show up for me so I don't think they have been deleted.
stop making threads asking for the same thing - bump a previous one you made...

You made all these within the last week..you could have had just one

e.g.

Weird, when I go to My Threads none of them show up, so I thought they were gone.

It won't come up under 'my threads'

Click on your profile and then click on threads

As Simon said(haha), if you go under "My Threads", they wont show up unless someone has posted in them after you viewed it last.

Just go to the "Threads" link in your profile
