lots of people type similar. in fact, many people type in all lowercase such as myself. you don’t know who someone is behind the screen. you don’t know someone’s identity from their typing style.
why do you think No Stupid Questions exists in the first place?? why do you think people ask for help/advice?? if they’re not going around saying rude/absurd crap or anything to get a reaction, it could just be someone with a weird question.
just because someone types similar to someone who was a troll or bad person does not mean that it’s their alt or that they are the same person.
i see this a lot with people assuming that account c is an alt account because account c and account a agree and disagree with account b, or because account b said something rude to account a and account c explained/defended account a. yeah, people can agree on something without being the same person.
if your comment gets -3 votes, it’s unlikely that 3 alts downvoted you, you just said something people disagree with.
What I can say is, sarcasm isn’t half as funny as you think it is.
It isn’t witty. It isn’t clever. It’s pretty cringe for people on reddit, which is why it gets upvoted so much.
Try to rise above that if you want to be better than it.
