What to do what to do

I have a few members that have wanted stuff. They agree to my price and the shipping. Send me their info, ask for my pay pal, then nothing. Should I put their info out for everyone to see? Then members can make their own decisions to deal with them or not? Is there already a list? I know that I have inquired about parts, then have passed on them, but I let the seller know that I’m passing on the part. Thanks. Kim
