I don't know who hacked the tree about, but the problem it uncovered was not worth it! For fucks sake, think before you start chopping bits of tree down. The new problem that has been uncovered is not worth a potential access problem at Eagle Tor. I noticed this block years ago, along with a number of other keen folk, but we thought we would not bother trying it, as we would have to cut part of the tree down.
Lets hope the lady who lives in the house over the back of the hill doesn't notice, as she'll not be best pleased to think that climbers have been damaging the trees. Its bad enough that we damage the ground and chalk the boulders up without making it worse.
