Kramnik has proven himself a troll and did a lot of damage to the reputation of honest and otherwise wholesome people and this without credible proof at all. That those allegations persist under the form of news article is very unfortunate to those victims of his smearing.

Being a "troll" connotes bad faith, i.e. not believing one's own accusations.

From the footage I've seen of Kramnik, I think he does believe himself, and is just generally very "salty" about losing (as the kids say).

I don't believe the strength of ones convictions factors into whether they are a troll or not. Take patent trolls for example.
