safety
The internet is just like anything anywhere. You don’t go into strange places and just lay your wallet on the table and walk around talking to people. Do you? You don’t just let some person walk up to you and sale you stuff that you do not need do you? When you drive through shady parts of town don’t you roll up your window? You don’t just pick up a random soda can and tilt it to get the last drop to fall into your mouth, do you? If some random person walked up to you and said “Hey, the police have your spouse and told me that if I collect $300 from you they will let your spouse out, and give them a steak and ice cream for your spouse’s discomfort”, you don’t just hand them your credit card do you?
No, you don’t do that.
Think of the internet the same way you do being out in public. Give nothing away until you are at a trusted website, in trade for something you actually came for. Do not impulse buy on the web. Do not impulse donate on the internet. Do not just throw your credit card number on any random website.
Stay away from shady areas, don’t just give out private information, and make sure your security and defense is up to date. The internet is pretty safe, unless you are just goofy and think everyone has great intentions.
