That was so long ago, it's just how people in contentious communities dealt with people to save work on mods.
I know because I was involved in those apps and moderating large subs that absolute shitmouthed turds loved to ransack with brigading.
You have no idea how bad brigading was, particularly by the foul, juvenile 4chan-type crowds who would arbitrarily decide something was "pro feminist" and then flood the sub with hate posts until the mods gave up and then they would slip in their own mods and rebrand the whole community.
I genuinely did not care and still do not care if it offended some people that they were pre-banned because they liked to participate in hate communities, for whatever reason. Back then you could make alts and nobody cared so what does it matter.
