And make sure not to click on any links. If enough people use chatgpt or other LLM’s to generate comments that are wordy but clearly just filler, it’ll give advertisers pause and tank the value of the site as training data. Reddit’s response will probably be to start banning users it thinks are doing this but normal users will absolutely be caught in the crossfire.
And throw in normal comments every so often too so it’s not that obvious.
You can also use this random gibberish generator.
I for one believe that scorched earth is the best approach. Your content is yours, you have moral and legal ownership over it; if you want to replace it in that site with gibberish, it’s your right and choice.
