We have no interest in being unfair, and anyone who genuinely wants to use HN as intended should have no trouble getting unbanned.

In this context, the test for whether an account is using HN as intended or not is whether it is primarily using the site for ideological/political/etc. battle. If an account is mostly using HN for the latter, which yours plainly is, then it's not using the site as intended.

I think that answers your question, no? It's not about buffer size, it's about what an account is primarily using HN for. It's supposed to be used for intellectual curiosity in a kind of meandering random walk. It's not supposed to be used for prosecuting fixed agendas, regardless of what the agenda is.
