Is RapidShare capping download speed for all users? - all rapidshare

I use rapidshare free for 2 months, and until recently a sharp decline in the download speed is was. Her condition and out of the past week was very good, but this week, which is still bad.
Many people are complaining about this in the forums, but nobody seems to have answered.

What is the cause?
