They can, like the data->>'content' up to the character limit but activities seem to mostly just have 'create' 'emojireact' and 'like' but a lot of that is already in the objects table anyway, and much more condensed.

Idk I just don't like the activities table. I think it's dumb if you're already going to do a lookup on both of them anyway and half of it is redundant data.
