I've sent an email to them last august 25. And here's the answer.
"Dear creator,
Sorry for keeping you waiting.
ā
July pledge will be processed, and we are currently waiting for Patreon to distribute the pledges.
Please wait a bit further, as we expect the distribution will be completed by the end of August.
ā
Thank you for your understanding."
I think they are just too busy. A the other said that they'll need to filter each of the comic manually by reading it (I think this is what they do )
