In fact you are probably safe even if you indeed was posting your identity!
I'm not anonymous at all. Anyone can find my real name and adress from my website (Link in the dropdown menu by clicking my name)
A lot of people here are not hiding..
Tory 'Magoo' Christman, she often posts her phone number as a means of help to doubting scientologists.. So does Chuck Beatty. And Arnie Lerma, Caroline Letkeman and Gerry Armstrong.. And DullOldFart who's posting above is not anonymous either.
I could list at least 30 people who are making lots of noise while standing defiently in the open.
Ok, while OSA really likes to intimidate and make us afraid.. They really are a paper tiger these days. There are way too many critics, ex'es and anonymous for them to do anything about... Heh.. They brag about 10 million members.. We can only find 50.000! - This must mean that 9.000.950 are unsatisfied customers!
And their organization is crumbling!
Which all means that you really don't need to be afraid of posting.
Staying anonymous is fine..
