I'll give you the same advice I posted in another thread:
"Legit buyers will probably only ask for 1 or 2 previews or a pic with written(photoshoped) writing. Just keep telling them 1-3(3 is generous) previews per customer. If they ask again just block them because they will just waste your time. Also don't bother talking to Indians or people from the middle east. Sounds a little racist, but trust me on that one. Don't bother with underage kids, I usually only talk to people that are 20+. The older the better."
Any more questions just ask :)
