== Sockpuppet == 

 Thanks for your message on my talk page about . I have blocked the account indefinitely. It may help to give you a few words of advice about how to handle cases like this in future. It took me a very long time to find evidence that the edits really were vandalism, and then more time to convince me that the account was a sock puppet. Many admins would simply not have that much time available to spend on checking a case. You said "The admins too much pity on him", but it is quite possible that they simply didn't see enough evidence to justify blocking. You would be more likely to get results if you gave some evidence. For example, Hayvan put at London Heathrow Airport that Turkish Airlines runs flights from Heathrow to Esenboga International Airport, Ankara. Eventaully I found http://www.heathrowairport.com/flight-information/destinations-and-airlines, which told me that this was not true. However, I rarely have any reason to check airline details, so at first I didn't know where to look, and wasted a lot of time looking in the wrong places. Clearly you have a knowledge of this subject, so you could probably have easily given a few URLs such as that one, which would have immediately shown that the edits were vandalism. Likewise, it is likely that you could have given reasons for thinking that the account was a sockpuppet. Quite a small amount of information like that would both save time and trouble for any admin looking at the case, and also make it more likely that they will block the account.
