I manually determined there was an individual posing as two people (playing both the antagonist and the adversary) because they consistently misspelt certain words such as "definitely" as "defiantly".

Fingerprinting certain linguistic traits and mapping that to time-zones as well as confirming there is a partial overlap in posts but never exact worked exceedingly well. Someone can't easily maintain a fluent conversation between themself on two accounts, but they can either get close, either through unnatural delays between sentences or just never interacting with the "other" party at the same time.
