I posted a question about MD5 hash collision back in 2014. As far as I know questions about algorithms are on-topic on Stack Overflow, and the cryptography tag did not have the warning "CRYPTOGRAPHY MUST BE PROGRAMMING RELATED" back then.

Stack Overflow is full of old "not directly programming related" cryptography questions, that are highly upvoted. Those have to be closed/locked as well?
