this happens because you post too much in one day, and the time lag is in use too quickly.
Another cause is also because the post in publishing is considered by SPAM moderator. Wait 10 days ahead.
if you repeat the same error it may be banned permanently
There is no rule saying you can't post many times per day. The rule is that you can't spam.
But if you're posting 100 posts per day, and you're using up that time lag consistently, then chances are you're spamming.
But if you're writing novels of relevant posts and threads during that time lag, then you won't get banned for it.
That's the way it goes.
OP was probably spamming hard or posting 1-word replies that don't add to the thread like, "I think that's cool."
