The comment from Ms. Peake was the kind of offhand association of ideas with no solid foundation as is used to spread nasty ideas about parties and just infiltrate the blogosphere. This tactic did not start with the internet or twitter but has certainly been magnified by it. It does nothing but spread a false association as if it is founded in actual research, which it isn't. The retweet on the part of Long-Bailey just makes it more indirect and harder to call out. It's the kind of incessant negative nattering that is at the heart of casting unfounded aspersions and builds an "attitude without evidence" and indeed got Corbyn called up multiple times.

Sir Keir called the situation correctly, as Griffith stated above. And the fact that so many people think that that kind of below-the-breath allegation is a correct way to behave shows how deep it's gone.
