I believe that a random person who sends you their outfit may just be fishing for likes, however, I would still appreciate their post my hitting that heart just to be nice. If someone has been following me for sometime and sends you one of their posts, then I think thatโs more of a friendly way of saying, โHey please support me!โ Therefore I would definitely like and repost. Lol sry for the long explanation I thought these questions were good since I wonder about them too :)
