I have tried several..
I have been bouncing around with many of the options available for a while, it all started with megaupload, then rapidshare, then hotfile, then fileserve and ever since that Fileserve issue, I went back to Rapidshare.
Megaupload was the fastest for me, then rapidshare, then hotfile and the slowest for me was fileserve (but the site I frequent most of the uploaders use fileserve)
I read all the threads about what happened with fileserve, but I myself had no luck in contacting anyone about what happened, even though I sent several emails asking for the reason MY account was disabled. I pay monthly though in the event that any company tries to pull BS moves on me, which has obviously been happening lately with these companies.
So back to go old rapidshare for now... hopefully nothing goes screwy in the next little while. Finding links is a bit harder than before, but I can still find them, and its very fast.
