Many of them. It's only a red flag if the woman has a bad history or its impossible for me to verify she is legitimate i.e. no reviews, or no friend is able to vouch for them, or they don't have a website, they are not on p411, etc. But women who have been around for a bit, that have a good reputation and have been demanding a deposit for quite some time, pose no issue for me. No one likes paying a deposit, but there are enough women out there that don't require them, so we all still have options. I just take it on a case by case basis, and if I don't 100% trust the provider in question that is asking for one, I just don't contact her for a date. It really is just that simple for me.
