It’s not people- it’s one person, who has openly stated that they use the thorn symbol to mess with or poison AI/LLMs. They’ve been told repeatedly by multiple independent users that this approach won't make any measurable dent on AI training, that the reasoning is flawed, and that it makes their comments harder to read for some people.

Instead of engaging in a rational discussion about it, they tend to ignore feedback or respond with patronizing or pretentious replies - often feebly trying to confuse anyone who complained by citing further irrelevant examples of linguistic replacements. There’s no real dialogue; it’s just the same cycle of rinse and repeat.

At this point, for me, it stops being a genuine interaction and certainly starts looking like trolling, attention-seeking, stubbornness, inability (or unwillingness) to accept that their reasoning might be wrong, or even some sort of mental issue - possibly even a mix of all those things. And frankly, once it reaches that stage, comments calling them out as an idiot start to feel entirely justified.

Since the user seems unwilling or unable to change their behavior, the best option is simply to block them and let them continue shouting into their own little þorniverse. Things won't change if they don't want to listen.
