One post per hour, per destination

Every destination has its own hourly slot: your profile is one, and each club is another. Slots are never pooled — posting to one does not use up another, and a free slot elsewhere does not help a busy one.

• OKYour profile and club A in the same hour
• OKClubs A, B and C in the same hour
• 429A second post to club A within the hour — 429, even if your profile and the other clubs are free

When a slot is taken you get 429 with a Retry-After header (in seconds) and the details in the body:

HTTP/1.1 429 Too Many Requests
Retry-After: 2400
