Just wanted to say hi to everyone!

I'm new to PTC and have joined a few sites and was wondering if they are scams or not.
Can anyone help me out please?

The sites I joined are:
twodollarclick.com
magicptr.com
richgoptr.com
paypermails.com
globalcashptr.com
dollargpt.com
aromabux.com
realptr.com

Any information on these sites would be greatly appreciated!
Thank you
