If you have the time to make ad hoc Hacker News comments in the weeds about the credibility of a link from a comment from a niche post, then you obviously have enough time to evaluate disparate pieces of evidence instead of trying to discredit them by applying blanket heuristic judgements based on seeming one-sidedness from a glance.

Nobody is saying you need so much spare time to rigorously analyze every source. That would be a disingenuous false dilemma. Instead, just apply slightly more effort than your stated dismissive heuristic.

Who’s trying to discredit them? I just asked if their claims can be believed. I thought “can I trust this random Twitter account” would be a completely standard question, attacked on the basis of “duh, of course you can’t, why would you even ask?” rather than because how dare I impugn the reputation of poor whatshisface instead of spending a couple of hours combing through the evidence for myself.
