Yes, yes and yes. Unless it is overrun/diverted by bots & shills, which is a corruption silently allowed by reddit to serve its corporate agenda. Reddit, being proprietary and closed-source, does not disclose the specifics of its voting system, which grants it some plausible deniability in the face of accusations of bias. Lemmy and Kbin etc have the advantage of being opensource, transparent, forkable, etc. whether or not you’re in line with its creator’s political standing.
