As long as a thread isn't self moderated by the original poster,then anyone and everyone is allowed to air their various views and as long as such inputs are on topic and makes absolute sense then it sure wouldn't be removed by a mod(as only self moderated threads can the OP preside over the discussions),and in the meta board selfmod threads aren't allowed
With that being said I do not know how according to you certain users are smouldering and sniffing out inputs from certain users as regards their original posts.
A user could add certain "clauses" to their posts and advice certain users not to comment on their topic,probably as such users find it difficult to stay on topic and not result in troll upon troll,and I've seen you add such clause couple of times,so I don't see any problem with it.
