when someone mentions Pearl Discourse i always think about how the MSPA forums have had a series of Vriska Quarantine Threads for literal years now because otherwise every discussion eventually turned into a giant Vriska argument
case in point:
these threads last 100 pages, or up to 2500 posts each before a new one is made. so it could be much worse
the mere fact this vriska argument went on for 42,500 posts and still going is a good estimate of human nature
To be fair, those threads pretty quickly turned into freeform chat threads for (mostly) Vriska fans, with actual arguments taking up a very small fraction of the post count
(The MSPA forums had a number of threads like this – in some periods the general MSPA discussion threads would fill up in a day or two, and were basically treated as forum-based IRC channels for a group of regulars, leading the mods to propose minimum content limits on posts)
So you’re saying Vriska discourse is the Katawa Shoujo generals of Homestuck
