Doubt it would affect ban rate if you selected the bot to dismiss them, 95% of legitimate players hate randoms and will dismiss or ignore them, unless it's an xp reward random like the genie. In my opinion people overthink these things, you really think Jagex is collecting all this data on whether people dismiss/ignore or complete randoms while training certain skills/doing specific activities? The osrs team is really small and they don't have time for these things. Yes they catch bots, but not because of random event data lmao.
