  In a recent paper, Ooguri and Vafa [arXiv:1610.04564] argued that a mild
extension of the Weak Gravity conjecture\cite{weakgrav} led to the conclusion
that the only models of quantum gravity in AdS space with "radius large
compared to the string scale" were models with exact AdS-SUSY. This note
clarifies certain obscure parts of their argument by reinterpreting it as a
statement about brane configurations in flat space. In that context the
statement is that stable non-supersymmetric configurations of branes are
characterized by charges in the torsion subgroup of K-theory and their only
long range fields are gravitational and scalar. The field equations do not have
large radius near horizon AdS solutions. Instead the horizons are Schwarzschild
black branes. This leads us to conjecture that for $d \leq 11$ the K theory
charges are bounded by a small integer, and there can be no large gravitational
back reaction in the near horizon limit, for stable configurations. Unbounded
values of these discrete charges would violate the Covariant Entropy Bound. We
discuss a counterexample to the conjecture in $AdS_3$. We find similar
counterexamples in higher dimensional AdS spaces, but argue that none of them
lead to SUSY violating models of quantum gravity in Minkowski space.
