1. Spoonfed rando amnesty. So long as they use the thread, or 4chan in general, then amnesty should be provided. 
2. No more spoonfeeding. Use the definition of rando "Someone who doesn't use 4chan" and use that to filter your acceptance/friends list. 

Rando problem solved. 

1. Is because you will get way too many problems with defining how long someone needs to have been using 4chan. 
2. Acceptance is used as a blanket term; you can still friend randos, just keep them away from here.

Main issue: Noncompliance. People who refuse to stop spoonfeeding will exist, either because 'this guy said nigger once he's cool guys' ignorance or doing it on purpose because it's funny. You just need to not accept the garbage these people bring in. Loose cannons can't stop this strategy.
