Those algos, ideally should weigh the twitter handle. Or else it's a stupid algo.

One need to spam through authoritative handles.

Pretty much like tricking google ranking algorithm with site-farms and fake backlinks. But hey, a lot of people were able to do this before Google started to improve its algo.

Twitter can’t even tell the difference between an “authoritative” account and whatever the opposite is.

If any bots are scraping twitter for altcoin signals, I would be pretty surprised if there were any checks other than num followers / join date / etc. Determining if a twitter account is a bot, even with minimal certainty, is NOT an easy project. And many of these crypto traders are not exactly John Carmack either.

Possible example: a few months ago when the price tanked after someone gave away < 20 Bitcoin on Reddit.
