The closest existing answer I could find to my question states:
Broader announcements not really specific to that community — DEBATABLE
But that was well over 2 years ago. Has there been a more definite consensus on how related the topic of a proposal and graduated site need to be before requesting a Community Ad for the proposal site isn't spammy? Is it sufficient for the proposal site to belong to the same category as the target site or does it need to be more closely related?
Here are some made up examples. If the following beta sites had Community Ads on Seasoned Advice SE during their proposal phase:
- Unrelated: Chess SE
- Both related to food: Beer SE
- Both in the same SE category (Life/Arts): Writers*
- Both in the same category AND related to food: Coffee SE
Which would be OK and which would be spam?
To be clear, I'm not asking how close they need to be in order for the ad to get posted; I understand that's up to each community. I'm asking about the appropriateness of requesting the Community Ad be posted in the first place.
*By category, I mean the categories used by Stack Exchange itself to group sites:
