Now, I'm not a big time seller, however I have been slowly cleaning out my closet and listed a handful of items recently. I place buyer requirement blocks on all my eBay listings to block users with unpaid item strikes and members without paypal accounts. I just checked my buyer requirement log and was shocked at how many users this was able to filter out. It looks like most of my buyers were blocked for unpaid buyer strikes--it's surprising to see the variety in users who have these marks--from low feedback to 1,000+ feedback! How do yours look? How many buyers have been blocked from your and for what reasons?
