From HN community guidelines on reading into a comment:
"Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize. Assume good faith."
If one store goes out of business and I say "Here are two store that I consider reputable for buying the same things", that really doesn't mean I think the original store was not reputable.
The comment does not at all read to me as justification for the ban one way or another. It is a simple statement that there are sources the commenter trusts on the topic, with a referral to them.
This is part of the reason why I detest Twitter's leadership. It's the tyranny of selectively enforcing the rules and hiding behind it. If someone tells me the same dozen or so twitter handles that always manage to chime in at the top of just about every trending social topic are authentic, I simply won't believe them. Why aren't these banned?
Well I can't disagree with that. It is endemic of Google, YouTube, Amazon, Facebook, Apple etc.
When these companies deal with the sheer volume of users they have they hide behind rules that are judged via algorithm and are not able to be evaluated or appealed unless you get enough attention on social media.
It is yet another argument for the elimination of them. If they can't manage themselves then they shouldn't be running.
There's no evidence this account violated the Twitter TOS.
