It's easy for newer members to not realise the restrictions here because it is so rare to talk about them here, so we aren't quick to punish people over it.
This section isn't called "3rd party" because that is just a Transformers fan term for unauthorised/unlicensed toys. In the real world, even in the toy industry in general, 3rd party refers to outsourcing or independent contractors for parts (like the BotCon exclusive heads & parts)... and in a way that's how Transformers "3rd Party" toys started, as (unauthorised) add-on parts for existing toys. When those unauthorised projects evolved into full transforming toys, the term just kept being applied, even though it was even less accurate.
Even though KOs are unauthorised, we have a special section for Knock Offs, for alerts and help requests.
