I don't believe they stop with pizza and triangle swirls. I think there are other symbols and codes that they use, and I don't believe it's a "witch hunt" to look deeper into those who are using other symbols/codes that appear suspicious based on other things we already know and/or have proof of. For example, I'm in a spot right now where I don't know what to do because about 2 months ago, I met a guy at a work social. He handed me his business card and it has the FBI pedo triangle as his logo, but slightly altered. I only encounter this guy once a month, so no chance to get to know him better or know who he's buddies with, but last week I saw him at another social and after a few drinks, he says to about 5 of us sitting around that his kid got into trouble for drawing a penis entering a 12 year old vagina. I and everyone were speechless, and I'm thinking, "How odd that he pegs an age to a drawing, and how exactly do you draw one that's 12 years old." So, now I'm in this predicament where I'm sure the dude's a pedo, but what do I do about it? He gave me a creepy vibe before I saw his business card, but what are the cops going to say if I request he be investigated for suspicious activities based on his logo, what his kid did, what he said, and his creepy vibe?

So, back to the thread topic, I believe that it's important to look at companies' logos, examine their activities, then decide if it merits a closer look or write it off as a coincidence.
