In a perfect world, I would agree that the work of a researcher who's not an established figure in the kernel community would be met with a relatively high level of scrutiny in review.

But realistically, when you find out a submitter had malicious intent, I think it's 100% correct to revisit any and all associated submissions since it's quite a different thing to inspect code for correctness, style, etc. as you would in a typical code review process versus trying to find some intentionally obfuscated security hole.

And, frankly, who has time to pick the good from the bad in a case like this? I don't think it's an overreaction at all. IMO, it's a simplification to assume that all associated contributions may be tainted.
