Taste is, as they say, very much a matter of taste.
For the same reason that you can’t tell somebody what they should find funny, exciting, scary or (dare I say it) erotic, what any one person finds annoying can often be something of complete indifference or even a source of absolute joy for another. And vice versa.
Of course, on social media, we see a little bit of everything. And we meet every kind of person. So, it lays to reason that we are going to stumble across people who, perhaps through no fault of their own (and, other times, with actual intent) we find annoying.
