A large wobbly block on the ledge at the top of this route has been reported to the landowner Eastern Moor Partnership.
Looking on the logbook there are comments regarding the block by ascensionists as far back as 2015.
I'll be taking a look at this tomorrow to assess the hazard and if/how best to address. I'll put some sort of insitu warning in place and would also request that climbers avoid the route itself for now, and avoid using the block if climbing adjacent routes (Topsail, Marie's Gone to Canada, Spinnaker, and Monument Chimney).
