Only the tags of the main post count. Commenting tags like #this does not get picked up by the HE stuff. But inherit comments on posts that have tags that triggers HE curation, will inherit all that.

This is why on snaps of peakd you don't have certain tokens curations, like MEME for example or CENT... etc...

Because on that container, only these two tags exist...
Although, if one wants to enable curation these, all they need is enable the snaps tag, and it will start enabling curation on the next peakd container.
