i was very badly burned in 2007-2008 by an online butch from another site who encountered me when i was at the very lowest i have ever been and created an illusion of dependability, which hy then used to browbeat me into free room and board and access to my bank account for a year.
i felt horribly humiliated when it was over, but when the exact same red flags came up in 2010, with someone (who was eventually and unrelatedly permanently banned) from this site, it only took me a week to spot it!
