@lauren Back in the day I wrote a "Candlejack bot," based on an old joke from a Warner Bros cartoon series... It just did a low-cost search for anyone mentioning "Candlejack" and interjected into their conversation (IYKYK ;) ). Just one "hello," then did not continue to engage.
... I got off the Twitter train long before they would have decided that was ban-worthy behavior.
(Hm... it occurs to me I should resurrect it on Mastodon. ;) ).
