I'm also really saddened by the situation. Like you said, we could have at least received a message from their part (even if it's an automatic one) just to show their acknowledgment of the issue.
I feel like the bad guy, having to resort to such measures (i.e by putting the share to 0% until a reaction from their part). I really love Itch and the community around it, but leaving us into the void like this is for so long.. that's just so unfair. It really damaged my trust.
I hope there will be soon a viable solution for everyone. Maybe that situation was caused by some new issues. But those need to be investigated and definitely fixed.
