Comments like above usually serve a couple of sentiments - not just pointing out the Striesand effect but attempting to amplify it. The trend I think got popular with the teenager involved in People v. Turner[1]. At the time there was a fair amount of fear that the case would be entirely buried due to his advantageous position in society (not altogether different than what is being discussed here). He also changed his name. So people would make comments like above on Reddit and other social media platforms as a sort of attempt to ensure that it be extremely difficult to erase attachment of the name from the incident in the future entirely.

You can see this at play still today anytime that teenager's name comes up on Reddit. Very typical example thread here[2]

That thread is pretty exemplary of the trend, someone will say "convicted rapist Brock Turner", and everyone will pile on and also state it, in some sort of attempt to continue to keep the association at the top of the search engine.

That being said, after it's been done once the original purpose is already accomplished and I'd consider it a pretty lowbrow attempt at humor after that. It probably would be considered low effort enough to warrant a downvote here.
