Anything Elon or crypto related is still being spammed heavily with giveaway/impersonation bots. Nothing has changed. The spam/bot problem is as bad now as it has ever been, and likely is worse than assumed, because it includes not just obvious spam accounts, but legit accounts that have been taken over by spammers or repurposed for spamming. So there is a % of accounts which are obvious bots and than another % accounts that exhibit bot-like behavior. Given how much time Elon spends on twitter and his first-hand experience with scammers using his name and spamming his comments, I think his assessment is probably more accurate compared to what twitter is claiming.
