@gpollara I think when someone talks about reply guys, they talk about particular behaviour. For example: centring yourself, contradicting the original poster (especially if they know more than you), telling someone's joke back to them, low or no-content posts ("I don't know"). All worse if there is a power differential, e.g. op is a woman, BIPOC, or LGBTQ+ and replier is a cis het white man.
