BuyerGuard от Arripis

BuyerGuard helps eBay sellers protect themselves by providing crowdsourced buyer reputation data directly on eBay order pages.

Features:
- Inline badges appear next to buyer names on eBay, showing their community reputation score
- Click any badge to see detailed stats: upvotes, downvotes, and flair tags from other sellers
- Vote on buyers (upvote or downvote) based on your transaction experience
- Add warning flairs like "Returns Abuser", "Non-Payer", or "Great Buyer" to help other sellers
- Agree/disagree on flairs added by others to build community consensus
- Works across eBay US, UK, Germany, Australia, Canada, and France
- Look up any buyer by username directly from the extension popup

How it works:
Install the extension, create a free account, and BuyerGuard automatically shows reputation badges on your eBay orders pages. All ratings and flairs are crowdsourced from the seller community.
