I did checked the rules and refrain from posting to sections you mentioned.
Do you know what Mega Threads are?
Thank you for highlighting the mistake I made.
As I said my purpose of asking this was to avoid this mistake next time.
So you're saying you let the campaign decide where you'll post? Why? It's totally fine to post in "Mega Threads" if you want that, and it's totally fine to post on boards that aren't paid by a campaign. You're supposed to post where you want, not where you're paid.
