I love the idea of a completely open protocol that thwarts spam by being unable to post any text at all, only tiny predefined pictures, aka emoji.

The obvious abuse will be, of course, pumping some counters to ridiculous values, making them useless as a measure of readers' reaction. Though it can be lighthearted fun in the spirit of the Web form 1994, I suspect that implementing caps could be useful.

Less fun could be posting tons of negative emoji (anger, crap, etc). Some site owners will limit the set of allowed emoji to only positive reactions, as seen in some large Telegram channels currently.
