Its not my place to say so but
Ass-kissing would be- "The gms are so freaking awesome, I can't believe they're doing such a great job. They're phenomenally superb; I can't believe I'm in such a great server...............give me kahos please."
A compliment would be- "The gms are doing a great job"
Both are compliments.
Difference- One is said something to gain position; it is not really meant.
The other is said from the heart/mind (whichever one works) and it actually meant.
Which one is used in these posts is up for you to decide; not that difficult.
To add something constructive to the post- New/Old gm team is doing a great job. Had my support ticket answered in under a day.
