Ebay Seller Blacklist

Ebay does not provide a way to blacklist sellers, so if you have a bad experience with a particular seller, you have to make a mental note not to buy from them again and hope that you remember their name. A particularly frustrating experience with one ebay seller made me decide to do something about this. Using the TamperMonkey browser plugin (available for most browsers), I wrote a simple "user-script", that includes a list of sellers. If the seller name is detected, it adds some flashing red text to highlight the problem:

If you want to use this script, install TamperMonkey for your browser. Once installed, click on the TamperMonkey icon in your browser and click "Create New Script". Delete the template script that appears and replace it with the contents of this gist. Then edit the blacklist seller names (defaults are just "seller1", "seller2" etc) to suit the sellers you want to avoid. You can include as few or as many sellers as you want.

If you want to use it on non-UK ebay sites, the line starting @match will need to be edited. I haven't tested it on any other sites so I can't guarantee it will work. Also, if ebay change the document class for the seller name (currently mbg-nw) or the document ID for the title (currently itemTitle) then it will stop working! If so, get in touch and I'll see if I can fix it.
