I don’t want to be a party pooper, but on the internet you don’t really know what motivates someone. I mean, I hope it’s all innocent but sometimes it isn’t. Maybe it’s better to not reveal too much about yourself until you trust the person asking?
Lots of threads lately asking people for pictures, where they are from, their interests, etc. If someone was data mining or aggregating information to build a dossier on people then they have a decent start.
