It is impossible to find where you broke a talent hub rule when all it says is:
It would help if there was an indication to exactly where you broke a rule in your 5,000 word talent hub profile… otherwise it’s like trying to find a needle in a haystack.
Try a “binary search” aka half-interval search, you can iterate the problematic word(s) in max. 12 steps. 
That won’t work. It doesn’t say whether the error is in front or behind the iterations. You need a linear search with varying character counts, which could take forever even with a supercomputer.
