i am not sure if you understood my points. you do not phrase them, as i did.
interactions are not limited because they are public. i said, that interactions are limited. what i meant is, that there are a limited amount of communication channels.
the current "block" feature of itch is an incomplete ignore function. a block prevents an action. an ignore does not prevent an action, but makes it invisble to the one that ignores. i argue for a better ignore function. and i consider a block function for the publisher side of using itch to be pointless. you do not even need an account to buy.
