Please give me some Forum Content Guidelines Clarification

I am looking to understand the content moderation guidelines as to why my rubber ducky debugging link to wikipedia was removed.

This rubber ducky debugging link to wikipedia was removed on this post. You can see the raw edit history. It was a simple link to a common programming term that refers to troubleshooting issues (which in programming is hard!) by talking it out as if you were talking it out with a rubber duck.

I then asked in that thread why it was removed, and instead of responding to my question was flagged as inappropriate and consequently deleted. No answer, just silent suppression. And just for a harmless wikipedia link and a question about its removal?

Please, help me out here.
