Ending a sentence with two punctuation mark

Hi,

I recently came across this sentence ("It intends to help answering the 
question I have a few hours for Debian, what should I do now?.") on 
UDD's maintainers dashboard[1] page. I tried to propose a change[2] by 
removing period punctuation mark. I've never seen people, in English 
writing ending a sentence with two punctuation mark (a period and 
question mark); to support my statement, I would refer to this[3] 
article of APA[4] style guide, hopefully other English writing style 
guides have similar rule. For more information, please see this[2] 
discussion.
