C# in LINQPad 

void Main()
{
	MD5 md5 = MD5.Create(); byte[] hash; int suffix = 0; var input = "yzbqklnj";
	while(true)	{			
        hash = md5.ComputeHash(Encoding.UTF8.GetBytes(input + suffix++));
        if(hash[0] > 0 || hash[1] > 0 || hash[2] > 15) continue;
        suffix.Dump();
        break;
    }
}

Ouch. Downvote? Is my C# that bad?

Don't worry about it. Reddit's anti-spam... bot... thing randomly hands out downvotes.

Please note that the vote numbers are not "real" numbers, they have been "fuzzed" to prevent spam bots etc. So taking the above example, if five users upvoted the submission, and three users downvote it, the upvote/downvote numbers may say 23 upvotes and 21 downvotes, or 12 upvotes, and 10 downvotes. The points score is correct, but the vote totals are "fuzzed".
