I must premise that the present OP, albeit motivated by a personal experience on Mathematical Stack Exchange, aims to solicit an open discussion about an important general issue concerning the common rules for a fair behavior in formulating comments on public chat rooms here on the Stack Exchange network.
For that reason, please do not focalize on the specific cases I'm referring to, but consider those just as a concrete example to better guide the discussion about the main questions.
Recently I have been suspended for 7 days for a comment in which I've expressed my own opinion about the lack in correctness and honesty by one user in his/her action on MSE. That comment has been considered rude and not tolerable by MSE Moderation Team, leading to my first suspension in 5 months of experience here.
Here below the message I've received on April 22 at UTC 6.18 PM from MSE Moderation Team to notify the suspension.
I fully respect the decision made by MSE Moderation Team, indeed my comment was of course out of place and eligible for some punitive/corrective action by the MSE Moderation Team.
What I can't really understand is why the same criteria for the suspension were not applied to a deliberate defamation action against my person perpetrated by some users and posted on public chat rooms named CRUDE and Math Mods Office which, I presume, are not aimed to manipulate someone else's reputation.
I’m referring notably to the following deliberate and reiterate public false accusations:
First remarkable defamation on March 15 2018 at UTC 2.00 PM on Math Mods Office chat room
Second remarkable defamation on April 21 2018 at UTC 6.17 PM and 8.11 PM on CRUDE chat room
Third remarkable defamation on April 22 2018 at UTC 6.17 PM and 4.06 PM on Math Mods Office chat room (2 hours before suspension decision)
Notably my questions are:
Why a rude but extemporaneous opinion given during an open debate by a comment can lead to a 7 days suspension while a purposeful, deliberate and reiterate public senseless accusations (i.e. defamation), perpetrated through public chat rooms, which should be aimed to different scopes, can be tolerated and allowed by the community?
Is that abusive use of the chat rooms compatible with the fair harmony of the community?
Am I overestimating that issue?
I've formulated almost the same questions to the MSE Moderation Team after my suspension, but up to now I didn't receive any reply about that.
With reference to the abusive use of chat room, I’ve received the following reply from SE support.

This kind of behavior is not forbidden in a general sense, but it has resulted in problematic behavior in the past. Ultimately, it just requires keeping a close eye. Most of these groups across our network operate in a way where they only target clearly bad questions or answers, staying away from more subjective materials. If a group ever becomes abusive and starts closing clearly good questions or doing other things that become problematic to the site, the moderators can always step in and intervene.
