Christ. Some people are willing to believe anything when it affirms their baseless beliefs. You’ve taken some reply that was about another situation entirely and let it convince you. I can think of multiple more likely explanations. Enough for this to at least be in the “who knows?” bucket.

Ye I had a revelation about something totally unrelated, when reading about one KPI hack, that the Reddit load new page upon clicking expand comment, also most likely is one.

What would be a good reason for that, that is not KPI hacking? The extra text is bogger all bandwidth wise.
