My android itself doesn't seem to want to display youtube to begin with, so I don't know much to do with that.
However if you 'want'. You can do this with adblock (implying you don't use it anywhere else).

What it does is turn on adblock for that specific site, in this case mmo-champion.com. Everywhere else it will be off. You can add as many sites to that code.
You may disable whenever you want, but that does require some extra effort.
Obviously fetching for the link is going to be a hassle.
