I don't mind screening if it's providing a reference, but there are SP's who ask for real names, work information, company links, home address and that is where I draw the line, and so should every hobbyist. Also there are a few SP's who do not accept certain SP's references due to many different reasons
Does it mean that some one like me who hobbies very safely and is a good client, respectful, shows up on time, never cancels will never see certain reputable SP's? Yes but it also means those SP's do not get to see me either which is totally fine by me and I have accepted that and that is why I don't contact any SP's who ask for such information. The SP's who ask for such information should be ok with not seeing me either and SP's trying to make hobbyist understand in post after post on why screening is needed will never change someone's mind who doesn't feel comfortable providing such information.
Personal information such as real name and work information should never be an option by any hobbyist to see SP's. Respect your time and privacy, black mail does happen in this industry and almost never gets reported by hobbyists due to many different reasons. The two sisters that were recently in the news in for blackmailing a Nigerian billionaire blackmailed many men in Toronto, but none of men went to the police to report it. So be careful with your personal information while hobbying.
No one knows the full story of what happened with the assault and robbery and we should not assume that the client was not screened, all I know is that is Delta Chelsea hotel at Yonge and Gerrard and a lot of indy SP's who screen often work out of that hotel.
With all that I said I don't think the ladies who screen need to provide their reasoning why screening is needed they just need to move on, and I also don't think hobbyist who do not want to provide such information need to explain as why not, both parties should just move on.
