A really weird thing happens. one of my user posted a question having a title beginning with quotation marks: "xyz"
Now this question got a very high view count now with more than 2800 views: http://www.gute-mathe-fragen.de/40224/redaktionelle-frage-wann-antwort-wann-lediglich-kommentar → I checked the server logs, there are just 10 calls of this URL, so I assume that there is an error in q2a itself?
To check, I just added quotation marks to this question title here :)
If anyone has faced the same issue, how did you solve it?
PS: From the question posted above I have removed the quotation marks, but the view count is still increasing a lot.
