Ladies, when dealing with scrotes, block them ruthlessly but wait to delete your conversations. Instead, post the gems in your local "Are We Dating..." group to warn other women and illustrate the level of degeneracy of these specimen so others wouldn'thave to indure their abuse.
If you are afraid to post them directly, dm them to those women who are asking for tea. Let's make the scrotes accountable for their behavior and keep each other safe!
Don’t delete messages between you. Screenshot them and keep it. Scrotes can and will come back to throw shade. Women aren’t believed when they are told that the men mistreated them in a relationship because he’s a “nice guy”
Keep yourself armed with proof and watch these losers know their place.
If it's something really sketchy or threatening, definitely screenshot the messages and his profile and contact details before blocking and deleting. That way you have something to show the police if he starts to stalk you or threaten you in real life.
i think this is case-by-case...some might need to delete for sanity reasons. HOWEVER, it might be a useful learning tool to deconstruct them, kind of like "decoding" OLD profiles.
