We ban accounts that post tedious ideological boilerplate and get into lame flamewars. People like to flatter themselves with "goes against the dominant ideology" rhetoric (I, the noble freethinker, unjustly suppressed by the servile mods, etc. - https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...), but really it's just tawdry internet stuff that we've all heard countless times.
That's why comments like this never come with links - because readers could then see for themselves and make up their own minds - https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que....
