Personally, the one reason why I like seeing those messages from bots is just "the confirmation it gives that I've gotten a particular token" but if there another way to go about it, I'd gladly hop on the option.
There are days I go to my posts and see comments-10. Out of the ten comments, the bots occupy 4, sometimes it's disheartening.
Token distribution through "award icons" similar to Reddit awards
this right here is a very feasible and nice suggestion.
