Almost no user has reached 200GB... Imagine what is 400 or 750... It is too much... Upload your files, see if you are earning money and space is available... Do not worry...
We mostly did this in order to protect our system from fraud as there were very few cases that were uploading TOOOOO much and had no sale... This costs too much for us...
Your accounts still have too much space and when needed more you just contact us
No way we will leave you without it

and further more imagine you are a DJ that uploads his new album of 400MB let's say... You can upload more than 1000 (THOUSAND) music ALBUMS...

There were cases that were uploading excessively... And do you know why...??? Because this way they delay our server speeds... Competitors??? Who knows??? If we let them continue, your customers (downloaders) would be disappointed from our DL speeds and this would be worse!!!
