Recent Regex Answered Posts getting downvoted

I know upvotes and downvotes are a part of the community, but this is something very, very weird.

Look at these latest regex answered questions (and look at the answers too.)

How to create a Regex pattern to change selected digits in a string

Why strsplit(x, split = “\\b”, perl = TRUE) splits at every letter instead of every word?

Why is this regex vulnerable to ReDoS in JavaScript but not in PHP?

All of these posts have at least one downvote… Even the ones with 5+ upvotes in total. I know that downvoting is normal, but this is becoming a little bit alarming.

Do I just ignore this or can I do something about this?
