When does social media advertising for a financial platform (Fidelity) become false advertising ?

In the war to acquire investing clients, have the largest players gone too far?

Here is an example of post on Fidelity reddit w/ headline “Decided to use Fidelity over Vanguard due to this reddit page!”

It was OPs first ever post, after account joined 11/23/2023

Mod response from a Fidelity customer care rep followed up with “Welcome to the sub; we're super excited to see you join the Fidelity family!”.

But here’s the interesting part- the Mod joined Reddit the exact same day – 11/23/23 as this account (who just posted for the first time with this fake customer testimonial).

Perhaps a coincidence- but appears to show Fidelity customer reps fake posing for a sub they mod on. Where do we draw the line when evaluating a company who is marketing financial services?

Putting aside the llm bots- how common is this type of false advertising?

Disclaimer: I am not implying this is a conspiracy or illegal- but fintech influencing is an active topic for regulators and one that impacts market integrity for all investors.
