They are just trying to take advantage of actual situation, but after other reliable filehosts will appear on the market ul.to just dies.
Teres why:
1) Premium user limited storage to 10GB, if you want more you have to pay a lot cash so noone will buy more space.
2) Premium user has limited download to 10GB/day, which is unacceptable according to today internet speeds. As excuse, they used lame argument that people were sharing accounts. Why they just dont implement that only one IP can download from one account at same time.
-=> ul.to = bad filehost
