I've noticed that once there are a certain amount of @pings in a chat message, the users who are mentioned don't actually get notified.
For instance, we sometimes have the bot ping lots of people for a Codenames game. The linked message consists of this, only:
@BusinessCat @Rubio @Forklift @JohnDvorak @MorganG @Deusovi @You @ffao @boboquack @thecoder16 @ConorO'Brien @Mithrandir @GarethMcCaughan @notjagan @dcfyj @micsthepick @Wen1now @cairdcoinheringaahing @Tumbler41 @Scrooble
I'm the twelfth ping in that message. I was in the room at the time - the message showed with the ping highlighted, like usual, but there was no ping sound and no circle appearing on my avatar. I've noticed this in the past as well, for mass-pings.
How many pings does it take for pings to be not counted as pings? Is it just a number or does it matter what percentage of the message is the pings? Is it all the users who won't get pinged, or just the ones past the threshold? Basically... what are the rules for when the ping won't actually notify the user?
