No don't publicly post where to get games. It is a common misconception, Roms are NOT legal if you own the game either. It also needs to be dumped by you as well technically speaking. Granted, they are less stringent and it is up to the publisher or developer to go after someone, but the guys who sell their old games (Nintendo, Sony, Sega), make DMCA claims ALL THE TIME. Some sites you may see will have an entry for the game, but no link because it was DMCA'd. Someone on one of our video's was trying to fight me on this. It is illegal, 100% as it stands right now and is certainly extremely grey (hence all the misconception like Abondonware is NOT a thing) and no matter how much other people do it (which was his argument). Chances are you wont get targeted by a company that is long gone, but you never know who owns the rights to what and had someone pee in their breakfast that morning.
I agree that Abondonware should be legal with proper checks and balances in place for companies who are no longer around so someone could for example, offer an alternative server to a game that doesn't have one anymore. Blue Burst is a server for Phantasy Star Online and it is extremely popular, Sega doesn't go after them. Blue Burst is technically illegal (unless they got permission, I have no clue) but Sega doesn't operate with Phantasy Star Online 1 anymore, they make no money off of it (except maybe merch) and thus they don't go after it. Just because there is no reason a company shouldn't go after you, doesn't mean they can't or won't.
