The QR code is a nice idea. I never used it, I usually use the old stickers that used to be on HP Micama's website.
I've thought about those possibilites, although not in such an extreme manner. What I do to avoid them is always go at night time, wearing dark clothes, and something to cover my head (like a hat or something), during covid time I would take a mask, you can still do it these days. Anyway just don't use the clothes you'd normally use, use some different combination.
I would never put stickers where there is people around, I'd go to places that were crowded during the day but empty at night.
Never go back to the same location to replace the sticker, in several months. This is a big town, so I always go to random locations and neighborhoods.
I usually put the stickers in bus stops, next to supermarket doors (if they have cameras, don't), sometimes next to residential buildings, and all over busy streets, next to school doors or nearby if they have cameras.
I have been using this system for years and never got caught. The point is to this in a subtle way, although some people sometimes see me, I was never recognized. Also it helps to act naturally, people do this all the time to advertise their businesses. Do not start looking around in a suspicious way as that will raise awareness from someone who is looking at you in a distance.
Some years ago I also tried a diffent method, I would print an entire page with information, put it on an envelop. Make hundreds of these and put in mailboxes, like if I was advertising my business or whatever, people do that all the time here. Just don't get caught by people who live in the building.
You need to be creative with this. Chances are nobody cares about what you're doing, but it could go wrong, yes. Specially if you're spreading stuff about the Yehuborim which can get you in legal trouble in some countries.
