I'll bite. FTFA:
Gergely sent an email to email@example.com on December 28, 2012 (which he later showed to me), describing the vulnerability in detail. After describing the simple trick, his email stated: "I don't know if this qualifies as a bug bounty bug, but I think it's certainly not in your interest to let these queries through. Using this method one can bypass all your numerical query filters, filters for SSN, TFN, credit cards, maybe DoS prevention and others I can not think of at the moment."
Gergely sent them a follow-up email on August 23, 2013. In both cases he said he received no response except for an auto-reply.
There's really no reason for the last two sentences to be in a separate paragraph, and this is something that is common in the way you write. From The Elements of Style:
"In general, remember that paragraphing calls for a good eye as well as a logical mind. Enormous blocks of print look formidable to readers, who are often reluctant to tackle them. Therefore, breaking long paragraphs in two, even if it is not necessary to do so for sense, meaning, or logical development, is often a visual help. But remember, too, that firing off many short paragraphs in quick succession can be distracting. Paragraph breaks used only for show read like the writing of commerce or of display advertising. Moderation and a sense of order should be the main considerations in paragraphing." (emphasis mine)
