If I am going to post a name selling shop.

Do I individually have to screenie each name, or can I send a pm/clanchat and take a screenshot after they all say like Sebben // On sale on sythe.

 

Unless I've missed something - I don't think I have - your method will be fine.

 

I think you have to.

You can take multiple screenshots and crop them. Paste them into 1 big picture and post it on Sythe. It's easier than uploading 20 screenshots.

 

sites like this encourage dont take a screenie so right the names then pm in game to prove you have

 

This depends on exactly what you are offering.

You see many times people have an "account name shop" where they simply list:

Bob
Joe
555
Hii
Yo
xD
etc...

And then prove directly to MM or buyer that they own. This typically happens for names that are still on tutorial island, have never been touched etc.

I believe you can get away with this method, however, if you have some very high quality names (or accounts with nice names) I would recommend the screen shot.

 

You don't have to.
