A few basic rules for mongering, most learned from mistakes made the prior 25 years:
1) Never use a personal phone or family computer! EVER!! (And I turn off and take apart my real phone a few miles away from destination because it is always tracked.)
2) Use a private PO box address on any and all hotel accounts and travel programs! This is CRUCIAL if you book a room!
3) Obviously ALWAYS use a fake email address. And try hard to never use this email address on any non-hobby website. (I have made this mistake...annoying!)
4) Use a burner phone, but only on event days, and keep it turned off and apart in a gun safe every day when not in use. Clean it after each use. If you need to save a number or name, do so via an email account as a note to yourself.
5) Use a proxy server for all such activities -- I use Avast proxy and log-in via a Canada address. (I forget sometimes, but try for 100%)
6) Use a track cleaner such as CCleaner, MacWasher, or WindowWasher to clean all cookies and history
7) When in doubt, manually clean history and cookies.
8) Use a code to lock computer when inactive -- I have fallen asleep late at night and had my wife or kids wake me up with my laptop open... but the screen had closed itself automatically.
9) I use P411 and do not meet anyone who requires my real email address, ID, or name. NO NEED, no exceptions!
10) Never use a credit card at a strip club, or when playing....Cash is king!
11) NEVER use real Facebook, LinkedIn, Instagram, or other social media. Set up another account if necessary. (Can be helpful in Asia and Europe.)
12 Have fun and stay safe!
I probably have a few others, but these are a good start.
