It's not okay. It might not warrant an infraction if it's their first time doing it, and they didn't know about the rule. We sometimes don't delete it if we end up attending to it after a few hours have already passed. @Psychotic ninja'd and got in there a minute after you posted it.
You knew about the rule, you're not exempt. If we said 22-24 hours to everyone, then wouldn't everyone just do it every 22 hours instead of waiting for 24?
