I've not noticed any changes in mine so far, touch wood, but that is fuckin worrying, you could end up seeing a barebacker/scammer or someone who arranges a mugging for you. Unless spotted as in this case though not sure how AW can stop it as even flagging someone using different IP address to log in woudnt be viable due to touring and logging in from hotels etc.
Wonder if there is a trade in punter profiles as well, if so just as concerning as well as nutters that have been blacklisted by the SP's could get another booking.
