I do see Waterluvian's point though. You might still have business with them yet you don't really want to deal with them otherwise. Knowing who this SMS or call was from can be helpful rather than blocking the number outright. Then again, seeing their name when installing Signal and figuring "oh hey they have signal too" seems no less weird to me than seeing their name in my phone book and thinking "oh hey they have a phone too". If that really sets you off... that seems unlikely. So I don't really get this subthread, even if I see the general point that you might not want to be reminded of certain people on a regular basis (for me, installing a phone number-based social application is not a monthly occurrence).
