A screenshot, taken way before rexxit, of two comments on reddit, dated "1 year ago".
The first comment is by a deleted user and the comment has been removed. The second comment is a reply to the deleted comment and it says: "That solved it. Thanks!"
This has been a meme for such a long ass time (even before Reddit) that any deleted post in a support type thread (or on a meme of the subject) was subject to someone replying "Thanks that solved it!"
