Drip is making me look completely ruthless for just dumping two allies who were at 16 and 23 days inactive.
I look at it this way: there are 4 ways you interact with your allies. 1) Use their helper squad, 2) they use your helper squad, 3) they spawn raid bosses that you attack for rewards, and 4) they can help kill raid bosses you spawn. Only #1 is meaningful for an inactive ally.
So if you find their squad still useful, then keep them on. Otherwise, I'd usually rather have the slot occupied by someone who is actually gaining something by attacking my bosses or using my squad.
I'm not completely selfish when it comes to my ally list; I have a lot of allies at relatively low TP who's squads I don't use. There's a few with very strange helper squads (5 4* at max evolved level, 5 event golds...when I know they've removed other better golds for those girls, and the crowning glory, the ally with Lycoris as assistant, but whose helper squad is 5 max evolved 2*). The only reasons I've dumped people is inactivity, although there are one or two on there on probation because of excessive damage to raid bosses (but everyone makes mistakes or has to learn so I leave some wiggle room there).
