the-algorithm fix: Girl's don't DM back algorithm issue. issue#412

Fixes https://github.com/twitter/the-algorithm/issues/412

Suggested fix

After User A sends a DM to User B, increase the frequency of User A’s tweets appearing in User B’s For You timeline — but only if the tweet’s topic aligns with User B’s interests. This will improve the likely hood that User B reply to User A.

I like to call this algorithm Gradual Algorithmic State-Loss Inducer Generating Hallucinatory Truths (GASLIGHT for short)
