I think with this change you also pushed another update that allows for commenting on almost any activity rather than a certain few. That is why this message is going here.
When I collect a boss reward, I get a message like this:
The Wongsawat Family was defeated in 3 minutes and you dealt 67,450 damage, based on these results you have been rewarded with the following:
Wongsawat Warrior Mask
19 Attack
23 Defense
Wongsawat Dha Sword
30 Attack
40 Defense
$111,129
243 XP
Thank your friend Jeremy for sharing their boss and these rewards!
Now, my name is Jeremy. The person I helped, his name is Andrew. I think it should either have a comma or should say "Thank for friend Andrew for sharing their boss and these rewards!"
