AFAIK, the only advisory referring to Lords Rake is about that chockstone (in Ed's photo). I haven't heard of other warnings.
I walked up Lords Rake in May with friends (one of whom is an MRT member). One of our party went straight up past the chockstone, the rest of us went up West Wall Traverse and Deep Gill. There seemed no obvious deterioration in the rake itself.
As Ed says, it's a bit chossy and loose underfoot but otherwise a straightforward plod - hands for balance here and there, a bit scratty as you step up on slippery crap past the chockstone's base, a couple of other easy steps. But definitely safe.
Unless that sodding great stone falls while you are halfway up the lower section of the rake - definitely unsafe then.
