Had it done to me a few times,was told by one mod that it was a "thinly veiled effort to put an ad up".when this was questioned by the fact that I'd not put up a number or contact details I was told "people could contact you via pm".what?try the for sale and wanted section,it maybe there,although if you mentioned that you'd got the parts from some vehicle that you've broken or obtained the parts directly to sell them then certain mods take SEVERE umbridge with that,something to do with trade rates!!!!
