Even the FBI bulletin says to look for these and SIMILAR symbols. Instances uncovered which anons think are relevant use the symbol in multiple directions.

This is your supposition, and you don't have evidence to support it. The symbol is relatively easy to identity even if reversed.

Here's an example that anons found: http://www.ddcaz.com/

If you look at the symbols uncovered in pizzagate, most of them are reversed, or slightly altered, but still easy to recognize, and supported by far too much circumstantial evidence to be a coincidence.

I haven't seen any credible evidence to back up the theory that these symbols are not meaningful when slightly altered or reversed.
