+## Rate Limiting of Support Requests through Temporary Blocking
+
+To ensure that the Renovate maintainers don't burn out from dealing with unfriendly behavior, those who display a bad attitude when asking for or receiving support in the repo will be rate limited from further requests through the use of temporary blocking.
+The duration of the temporary block depends on how rude or inconsiderate the behavior is perceived to be, and can be from 1-30 days.
+
+If you have been blocked temporarily and believe that it is due to a misunderstanding, or you regret your comments and wish to make amends, please reach out to the lead maintainer Rhys Arkins by email with any request for early unblocking.
+If/once you are unblocked, you should edit or delete whatever comment lead to the blocking, even if you did not intend it to be rude or inconsiderate.
+Long emails or apologies are undesirable - the maintainers are busy and want to be able to help as many users as possible with the time they have available.
