There are some simple ways trolls use to make themselves think they are smart or winning arguments.
1). Claim they have information that they cannot release because they would get into trouble.
2). Claim they have multiple science degrees and others don't understand them.
3). Claim they have information but constantly, for weeks, claim they don't have the time to post it.
4). Claim they do not have the resources to perform experiments.
5). Claim others are stupid and ignore direct refutations all while claiming those refutations are derailing tactics.
6). Immediately resorts to insults when they cannot rebut.
7). Claim they are using logic when they are clearly not, claims others don't know logic.
. Puts others on ignore lists because they get tired of repeatedly being asked to clarify what they are saying, so they claim those people can't read.
There are many more, but I think you have hit a few of these Mr. Itchy.
