Sorry, but it’s FR’s rule, not mine.
It's your interpretation.
And if you aim to be the link police, I could but won't point out a few dozen forbidden ones you've missed.
My recommendation is to either hit abuse on that post, yourself, or just drop it. Same for in the future. No need to announce it, discussion just creates (minor) distraction in the thread.
We mention 8 chan here on a regular basis, we copy paste from there all the time. If the link isn’t live I fail to see how it matters one wit.
