I can't dispute this, but since you shared an anectdote I will also. I haven't seen this in any of the communities I visit personally. Do you mean bot accounts which are passing themselves off as real people and karma farming? Or bots that self identify as such to fill a legit need?
not out to defend reddit here, it also feels to be going donwhill to me, but this is not something I've personally experienced on the site yet
