The question Does encrypting the key with itself make it easier to crack the ciphertext? was closed/merged with the question Encrypting a key with the same key using AES.
However, I do not see a reason to that, since the first question was much more general than the second one: In the first question, AES was cited only as an example (this is what "EG." in the first question stands for), while the second one was entirely about AES.
Moreover, the answers that the first question had received (Luis Casillas' answer and mine) not even cited AES, which means that anyone accessing the second question now will see a question solely about AES and two highly upvoted answers that do not discuss AES at all.
