I do a lot of Priceline bidding for hotels. I have in the past used Biddingfortravel a lot. But no more.
There have been 100's of members banned from that site. Mostly for small mistakes. One person I know was banned because he was asking travel or bidding advice for a relative or friend that did not use a computer.
Not bidding through their links will get you banned. Not a warning. A ban.
I know use betterbidding.com. They have more posts and threads and are not "ban happy".
This recent and on-going thread from FlyerTalk is well worth reading.
Continue to post there if you desire. But do read those long FAQ's first and then again.
Any mistakes will get you banned.
