Not sure, but I think she is the same girl. All my links to the old galleries are gone; her nicknames were never the same: Silvie, Bitsa, Liz, Megan.. there was a set with her and Jana Mikusova, one with a skateboard, one with a washing machine (probably the last of tumulpi post) but I can't find them anymore. Her sets, I was able to find, are solo or with others girls, never hardcore.
Ahh, lovely....
