Yes, something else to reassure potential buyers that they aren't going to get ripped-off!
There are several red flags here, any one of which would be cause for suspicion.
1. You just signed up at CF yesterday
2. Your Paypal is unverified with 0 transactions
3. You keep pushing for a quick sale
4. You keep dropping the price
5. You can't/won't do the transaction via Ebay
These could all be coincidences and justified by other explanations but they are certainly cause for concern.
