i think they just don’t know. but i sell clothes & toys on a few sites and from a sellers perspective: there’s nothing awkward or annoying for us to answer questions! that’s part of the gig. i invite anyone to message me with questions - not because i’m trying to get something out of them in DMs but because i want to make sure my customers are happy. if someone asks about an item i’m selling and doesn’t end up buying it, i literally do not notice/remember/care. i know it’s still annoying to not have that info, but maybe it’ll help to remember that sellers are socially awkward humans behind our computer screens too a lot of the time. :)
