A funny case study with Internet trolls: a Polish company selling a Signal clone sued security researchers who pointed out some security issues. The company also led very aggressive PR campaign, with dozens of YT influencers, hundreds of fake "this app is great" comments under articles.
People promptly noticed all their comments can be easily identified by an unique feature...
Most of their comments have used Unicode HORIZONTAL ELLIPSIS (U+2026) which is a single … character instead of ... (three ASCII dots) which you would normally type in a comment field.
A working theory is that they were writing these comments in Word for accounting 😂
TBH I suspect it might be also a some mobile OS with auto-type feature, because I saw comments using U+2026 that clearly weren't from that group.

I only type “...” (three dots) when attempting to impersonate someone.
