No it is not. Trent posted something similar which stated that RID is offering free service until the beginning of the new year.
Completely fake, at least that's my best answer best on the info you provided. Don't quote me on this, but I'm certain that RiD bots connect to a server in order to run, so therefore a free version (AKA Cracked) is completely fake and only wants to steal your account and maybe even your real life info (CC numbers, SS, etc) Report that PM to a mod. If you want to get this "free RiD" then by all means go ahead, but it is most likely not legit.
Ignore the pm. You shouldn't have to subscribe to anything to get the free RiD that is currently being offered.
Anything being offered as a Cracked RiD is a scam, always use the official site robotzindisguise.com (I can remove the link if it is considered advertising). As a general rule I never trust youtube downloads anyways especially when they are offering something for free or cracked programs. As for RiD he is offering a week free of botting but you dont need to download sketchy files or use a secret login just register at RiD and enjoy the free premium bots.
As a side note he is banned from RiD and should be banned from sythe as well for spreading phishers. So much for his free week of botting
