Please consider reopening https://math.stackexchange.com/questions/3302207/looking-for-a-simple-proof-of-the-divergence-of-the-prime-harmonic-series.  It is a natural question of wide interest and has a very clear implied context, of a teacher who wishes to present an elementary proof of a famous theorem to calculus-level students.  It is not clear to me what additional context the close voters would have wanted or how the site would be better off without this question and others like it.
