Breaking light scources

[NLewis]

I do not quite understand how this is breaking the rules.... I simply put out fire, I did not break any blocks, take down any torches, or do anything against the rules to that matter. It was not my intent to make creepers spawn, but instead to wreak havoc in the fort of Natain and Alphonse.

I see now that I am ban for 1 week. This does not make much sense to me....

Could a mod please explain?
