OP tried to express their opinion on how to avoid a red tag. But the red tag isn't limited to a few reasons. The only reason is red tag is involved with shady activities. Don't involve yourself with the crime, that's enough to avoid ref tag. We know which is good and which is a bad thing, so those who are getting tagged are well aware of it. Like when thieves steal something they know very well police will arrest them in case they catch them. So the only policy is don't involved with crime to avoid a red tag.
