To clarify, links aren't banned here (unless there is loli, which it was rulled one of the mist sisters in fairy fighting was.) it is link begging that gets people banned. You can share whatever links you want, it's just if other people beg for them they will get banned.
With mediafire, an issue you might run into is that thanks to some events years ago, when they decided we were a hub for piracy (which to be fair, there is plenty of piracy here), mediafire will block any links that come from this site. This means that if you share mediafire links, anybody that wants to use them will need to copy the link and post it into their address bar, rather than click it, so that it doesn't get linked from ulmf, which mediafire will just block.
