There's a common behavior on the intarwebs that we need a word for.

When you ask for advice on how to do or avoid doing a thing, there's a category of person who will invariably respond by questioning your desire to do or not do that thing. Often aggressively/defensively, as they themselves are invested in doing the opposite of what you're asking about.

Examples from my own experience:

"Now that ebay will no longer simply credit a card, is there a way I can sell on ebay without giving them my bank account info?"

Response: replies from people who insist there's something wrong with you for not wanting to give ebay your bank account info. Nothing actually useful.

"Does anyone know of a decent webmail server that's not written in PHP?"

Response: Whole lot of deeply butthurt "what's wrong with PHP????!!?!?!" replies. (Answer: far too much to go into.) Not one useful answer.

What people like that need to do is not reply. Y'know, because that's what you do when you don't have an answer. But instead they go for the hard derail.

Sealioning is a great word for a certain kind of reply-guy behavior, that of badgering you to engage them on something you've said or which they've chosen to infer from what you've said. This isn't quite that. It is however bloody irritating.
