Her is ebays answer to the limited buying. So new buyers can only buy 7 items until they pay for them and build a reputation. Do you like it?

Thank You for writing into eBay Customer Support. I'm Luke and I am
happy to assist you with your concern regarding bidding limits.

I understand your concern regarding your buyer reaching Buyer Activity
Limits. I am pleased to help you in this matter. In efforts to promote a
safe and successful trading environment, we have limited the amount of
items purchased by a single account at any one time. This limit is not a
reflection of your status as a member of the eBay community.

We limit the amount of items purchased by a single account at any one
time and impose buying limits related to changes in an account's
activity. This allows buyers to increase their ability to purchase items
in relation to the volume of successful transactions they complete.

We encourage you to complete the transactions in which you are currently
involved and return to buy and sell more items in the future.

If you have additional questions about the buying limits on eBay, please

I appreciate your understanding regarding this matter. I wish you luck
for all your future transactions on eBay.

Regards,
