Jorge,
I've missed to say we discourage hotlinks to external sharing sites and companies official sites, and that's for safety reasons.
The fact this forums allows hotlinks doesn't mean anything. It's our choice, cause we have had problems in the past.
This site offers that option and it's something we just can't remove (I think), but we try our best to try avoiding potential threats.
Hotlinks to any other site like Discogs, or Youtube (through embedded video too) it shouldn't be a problem.
