The 1x1 to lock you out of your Mediafire-Account:
- Change password to a new one with more than chars (works)
- Try to login with it. 😂 (too long)

Had to reset it and set a new new one with 30 chars.

once I downloaded a zip from MediaFire from an "idiot kid" (you know the kind) and I opened it. The format was invalid. I open it in notepad and guess what? IT'S A FUCKING RAR FILE! so I rename the extension to rar, lo and behold, yeet, it works. Don't trust idiot kids. ever.

So I live in the middle of nowhere and therefore I have a very limited choice of different ISPs. The short version of the choices is a fast but very limited in data size or one that works 99% of the time (I'll talk about the 1% later) but doesn't have limits on downloads. So I obviously chose the second one.
It works pretty great most of the time and I don't have any problems usually... The problem with "usually" is that the 1% of the time it doesn't work is all it needs to frustrate me. I could be downloading a massive file and around 70% the Internet decides to disconnect. It wouldn't really be a big deal if it wouldn't cause the file to get corrupted.
My point is that if you're going to share a big file, don't upload it to mega, mediafire, dropbox or anything like that. Just use torrents. They work way better for big files.
