I think it is in the interest of the grindr community's safety to create a "Block user and any accounts they may create" feature. I've been harassed by several people who simply make a new blank account and then approach me in app. They make new accounts almost weekly and their undesired contact has persisted for going on two years. I block them every single time. Once he even catfished me with other people's pictures. I highly recommend a feature that links blocks accounts by registration information so that undesired contact is limited.
