As Actually already said, those posts were removed or PMAd because they violated the "terms of service." 800 notes is a USER driven forum but there are rules and if we violate them our posts get removed. The users and posters on this site are taking a real bite out of the criminals who commit these crimes by making people aware of these scams. So chill.
Now, as for this number, it's the Reward Redemption SCAM. Here's some information:
It's the "Lisa (or Julie or Andrew or Rachel) with Rewards Redemption" SCAM. You’ll be told they have a gift card for you (usually $100) for visiting one of their sponsors sites recently. Later on you’ll be asked for your credit card number to cover fees. It’s a big SCAM. Block it. If you want to have fun with them, ask them to take the processing fee out of the cards and just send you the remainder.
