Welcome to paypal , unfortunatly it never matters to paypal how long you have been a member or how positive your history is they will always surprise you with a naughty little reason to deny your access to your funds.
They claim that this is for security reasons and that other companies do the same but this is a flat out lie .
I have been a member for over 2 years , i signed up mostly because ebay had the silly requirement that you had to have a paypal account in order to sell ( luckily they got smart and kicked this requirement and now paypal to the curb ) first they started to put a hold on every transaction , ok i did not have a problem with this because the account was new and i had no feedback or selling history on ebay , then eventually they lifted the hold policy but now almost 2 years later they started to impose holds on larger sales which once again i understood because the sales were much higher than my average ticket but now they changed policy again and impose a 7 day hold on every ebay sale not just the big ones .
I have a 97% positive feedback rating and had no chargebacks and only one or two disputes, i also have a merchant account with first data , the processing volume with them is significantly higher than what we process with paypal , we never had any issues with our merchant account and unlike paypal they transfer the funds from every sale directly into our checking account within 2 Days !
If you are selling on ebay quite a bit you really need to look into getting a merchant account , there is a wealth of companies out there offering merchant accounts for small sellers at reasonable terms and much lower fees that what you pay with paypal
