I don't know how I feel about this, I understand their logic, but don't necessarily think it's always a bad thing. I'm in the pet niche, what if I find a veterinary oncologist to write a post? I get the ones that are peppered with links are spammy as hell, but I don't think all guest posts are bad. I wonder what is next though? I had a vet ask to write guest posts for me and I said 'no', but instead asked if he'd review/fact check my medical articles, and for the ones he has, it will say 'reviewed by Dr Joe Bloggs of J Bloggs Vet Practice, with a link to his site.
