¡This is very interesting idea! I am thinking about this since long time. ¿Is very possible that affiliate disclosure is signal of host longevity?
I write long thing then delete. Jajaja. Here is short.
I check 24 hosts from this forum. 18 with disclosure still operating. 6 without disclosure, 3 dead, 2 sold, 1 "rebranding" since 8 months. Data is very imperfect. Small sample. But suggestive.
My theory: disclosure means planning for future. No disclosure means exit preparation. ¿What you think?
