Hello community team

I'm afraid I'm banging on about the same old subject, because nothing is being done. 
I've previously said I wouldn't bother reporting these issues anymore, but last week 

I reported a seller last week who has at least 3 shops, all selling similar items, at least 2000 listings in each, is a 'private seller' and doesn't accept returns. 
It is incredibly frustrating that eBay isn't policing their own site, but my question is why do these sellers continue to get away with this obvious fee avoidance?
