Yes at least tainster and the messywrestling division do reply to emails. Though I think they just give standard - we will pass on the request - replies. Whether they do pass the requests on or not, who knows.
Seems like tainster is the only adult work she did when all her friends have shown up on sites like czechcasting and united modeling agency, and are still active. More likely that a friend got her to do some tainster work for quick money and all that she did was filmed a long time ago and she is done now.
The ph and dso scenes with her are probably done. We got a new messy wrestling with her a few weeks ago, but it was probably filmed months ago. Hopefully they have more that are coming in the future, but at this point it isn't looking good.
They only thing I'm hoping now is maybe messy wrestling has a topless oil wrestling match waiting to be released, but not getting my hopes up high for that anyway.
