You seem to be in denial of what the issue here really is and why you've made a joke of yourselves. Itch,io wouldn’t let you upload more fine, why did you think Telegram a service which requires your long time supports to hand over all their personal info and phone number to access it when and then still can’t download anything was a better option then uploading the archive to a file host and then only allowing the access links to the relevant purchasers. That is easier, that is better for your supporters, that wouldn't trigger any blow back and its what most other decent sellers who have this issue go to. Your method is to block out your old supports who don’t yet another account or to use a dubious company who wants all your info.
