Trolls can't say they're trolling. :) What would the fun be in that?
And if you've never trolled, which (in my opinion) I respectfully doubt, then you should. Although, this being the politics page, it's best to do not do that here.
Trolling is an excellent way to get attention but, it rarely results in anything productive.
I've yet to see any studies where trolling reduces the cases or deaths of covid. Nor is it very inclusive in getting other people to understand your perspective, nor is it very informative in regards to facts.
However, trolling is quite excellent at relieving some of your personal frustrations and, indeed, entertaining a few people who are only in on the gag. However, in the end, it just makes the troll look like an ignorant idiot after time passes and the gag is long forgotten.
