I may have read something about this on Atom, where a company changed their logo to match the Atom logo, and I recommended the domain owner keep records in case the company was trying to pull a fast one.
Personally, this recent "logo fest" on marketplaces is the most short-sighted crap I've ever seen, but all the nitwits are wasting time and money generating logo after logo after logo like it's some kind of weird game. I see no real benefit (we're selling domains not logos) and a ton of risk, as evil corporations will grasp at anything to steal valuable domains.
I never use logos and never will.
