CCIP-084 - Clarify CCIP-069 and remove Sponsored Posts after six hours

Sponsored Posts need clarification as to what happens to them after the six hours are up. The options are:

• Leave them up after six hours
• Remove them after six hours

CCIP-069 is not clear on what should happen to Sponsored Posts after the six hour period. As such if we take it at face value we should leave sponsored posts up after six hours. I am proposing that we remove all sponsored posts after the six hour period.

Hypothetically if a single advertiser purchases every sponsored post slot over two days, and uses the same template for every post. Than there will be eight identical posts on the sub over that two day period as a result of the sponsored posts and they would all be up at the same time.

This hypothetical situation does not sound enjoyable to sub viewers and as a result is not ideal. In order to prevent this problem we could remove duplicate sponsored posts and keep one off sponsored posts - however this solution is not consistent and presents multiple potential problems for advertisers who purchase multiple slots such as:

• You are encouraged to only purchase a single slot so the post stays up for longer
• If we remove a hot post in favor of a new sponsored post slot, it could actually result in less views for the advertiser.

In order to prevent these problems and to be consistent I am proposing that all sponsored posts are removed from the sub after six hours. This way all advertisers will be treated consistently and we are not prioritizing one off sponsors who get to keep up posts for longer. Additionally if we remove a hot post in favor of a new post it isn't hurting the sponsor as that is what would happen regardless of the amount of slots that the advertiser purchased.

This clarification in rules will allow us to better advertise sponsored post slots and will allow us to treat buyers equitably regardless of the amount of slots they purchase. (currently we either risk spamming the sub or treating one off sponsored post purchasers better)
