Martin...no, not to the levels as such, but to the method of 'update' handling.
I just updated my WinAMP skin and found it in the WA-pending section, myself...
I'm not totally up-to-speed with the mechanics, but the system is intended to help control 'update abuse', where some have been found to needlessly push updates through frequently to inflate their download rate.
Neither you, nor I have had our levels 'altered'...we haven't upset anyone...
