This is an official program being run by eBay on the US site, and possibly the UK site as well as shown in the linked article above. There's a ecommercebytes post about it as well, but my links to that site always result in an error page, no matter what (no idea why). 

I'm not sure the program has gone down too well with the majority of eBay users - those who spend time assisting for free often resent those who are being compensated, and the whole "being paid by eBay" idea has already re-ignited ancient conspiracy theories here in this forum. 🤣
