Please be aware that there are people on the interwebs that will dox you. Dox, means to look up on databases all of your personal information and post it publicly. Usually the people who do this are internet trolls fortunately that are laws (identity theft, cyber stalking) that can deter this, but there are instances where it does not.
I was dox'd last week and threatened by someone who purposely attempted to goad and bait me, all because I refused to fall prey to their snarks. They did however send creepy and threatening messages to me. They have been blocked and all the messages have been kept the police will be notified if they should attempt contact again. This person was/is unknown to me and wanted to debate me politically but became vicious when presented with facts.
Play nice, use caution and walk away if someone attempts to goad or bait you off topic.
