>If Robinhood continued to allow trades then they could be accused of being complicit in market manipulation.

They can be accused of anything but that doesn't mean it will hold up under any scrutiny. Brokers aren't obligated to make decisions on market manipulation -- that's the SEC's job, who does it quite poorly as we can see from this episode.

Yep - surely a broker cant be a party to manipulation by simply offering their brokerage services!

Stopping the purchases of a share unilaterally, on the other hand, would look like manipulation.
