Hi,

We've hooked up Bulter to our Jenkins server, and it pushes an automated build into our private (password protected) itch page for playtesting and QA.

Currently, builds are about 1GB, and it looks like patches are calculated locally and often less than 1% of that actually gets transmitted. On average it's probably 10 to 20 times a day during office hours. 

I think the likely answer is that this is so little on the scale of the entire itch.io domain, that it doesn't matter. Still I want to make sure we're staying with in terms of use, and general acceptable policies, but I couldn't find any hard numbers on that. 

Are there any limits (reasonable, ethical, legal) I should be aware of?

I’m not aware of any hard limits. You say “every commit”, but are those commits to an unstable development branch, which might get many pushes per day, or a stable branch, which might get a push every few days?
