Black holes are how I remember which one is which. But I would rather not have to think about it.

I agree, if I was writing new software, I would probably use a more descriptive term if and where possible, e.g. blocklists instead of blacklists, it is a good practice to use descriptive names anyway.

I don't plan to edit and rename things within my existing software as it would add needless churn, risk, and the risk-benefit analysis just doesn't support it for me. Not saying that my analysis is the same for everyone else.
