Burst posting is not against the forum rules. PP's posts (regardless of timing) are not shitposts and in general are positive contributions (IMO) to the forum.

Asking someone to adjust the timing to fit the advertising needs may work for shitposters - they can easily smear their shit around in thin layers with no impact to the already abysmal quality. Asking a non-shitposter to do that is counter-productive, because they're usually replying when and where a reply is appropriate, whereas replying one hour later may no longer be relevant, result in repetitive posts, etc. I can't imagine that being any better for advertising but what do I know, maybe shitposting is good for advertising.

Yes, I'm aware that ChipMixer has the same rule and I think if I'm asked to adjust the timing of my posts then my response would be similar to PP's. However I always thought that burstposting rule was there to discourage users from trying to max out their quotas by making 50 posts late Friday, not to police their otherwise healthy posting habits for better ad exposure.
