They are like cockroaches that simply cannot be exterminated - and the only thing that would have an effect, in my opinion, would be blocking keywords, instead of which something like "shilling banned" would be displayed. It may sound too radical, but a company that pays for this kind of advertising does not deserve better treatment.

However, one more important fact should be highlighted, which is that we see that some more experienced members knowingly/unknowingly participate in shilling by entering discussions in which they should not participate.
