I would suggest that that sort of behaviour merits (some warning, and then if no change) a ban.

Having no magical moderatorial powers, I'll have to settle for just downvoting the offending comment and would encourage others to do likewise (if they are willing to believe ChristianKI's statement about what Clarity did).

Entirely tangentially (and with apologies if I cause offence), a linguistic note: English uses the gerund (Xing) rather than the infinitive (to X) in the construction "stop ..." -- we would write "please stop editing ..." rather than "please stop to edit". I'm not sure exactly how this generalizes -- you could say either "start editing" or "start to edit"; either "cease editing" or "cease to edit"; either "I like editing" or "I like to edit"; only "I have to edit" and not "I have editing". This may be of interest but doesn't shed much light on why you can "start to edit" but not "stop to edit". When I started writing this paragraph I hoped to be able to say something more general and therefore more useful, but having got this far I'll leave it in even though it seems actually to be quite specific to the verb "stop".

I assume Clarity has rewritten their post because I can't clearly see the offense after skimming the links. Or what did I miss?
