Don't take anything (or anyone) too seriously.
Always keep a sense of humor.
Be skeptical if in doubt that there is a "real" person behind any profile.
Fact check any advice you plan to take. (In fact, fact check the advice I'm giving you now.)
"Block Him" and "Ignore His Posts" is a great way to have the most pleasant RJ experience.
And, for the anciliary RJ dwellings (and there are anciliary dwellings), you might want to consider abstracting your real life identity.
Other than that, HAVE FUN! (and stay out of the "shade")
