I did use mediafire over two years ago, links started being taken down for "copyright" although I wasn't uploading whole games or anything like, probably just the naming system I was using which was including the name of the game the model was from.
Apparently my links are banned at the moment because of a hack I did for Super Mario 64 to change all of the songs to use Mario's sound bank (Super Mario Choir 64 is one of my most popular videos, such a simply thing yet everyone loves that more than my other stuff *confused*), going to have to look into seeing if I can make that a ppf patch to upload as apposed to just uploading the rom. Was most likely flagged because the only thing that was changed was the music, everything else was the same besides also having a version with Staraxxon/Vl-Tone's Luigi model.
Sure it says too much traffic, but I got an email about the file so idk if both are a problem or if the "too much traffic" is a coverup for what really is the problem. I deleted the file and the email said that the links would be fixed if I removed the file in question so I guess wait and see if the links are fixed over the next day or so. If not, probably will have to look into either making another account that is paid and thus can handle more downloads & bandwidth, or look into some other website.
Didn't know that Dropbox actually dealt with copyright, will have to be more careful about my SM64 hacks as I never looked into making ppf patches and don't know what the limits are. SM64 hacking is one of the first things I started doing regarding YouTube and just hacking in general, God I miss 2010 & 2011 where I could focus on just one thing which at the time was SM64, now I'm spread way too thin with just Brawl hacking alone, then throw in the other things I do on YouTube.

Ah, i see. I just realized you are the same one who uploaded that Mario 64 mod, I actually uploaded the individual Choir tracks on my channel. Anyways, i think if it isn't the copyright then it might definitely be the high traffic because i saw some other hacks on Brawl Vault with the same issue and Dropbox seems to have a traffic limit of 20gb per day for all your downloads and 100,000 downloads per day without you getting a ban on that account.
