It looks as though your friend request was still pending on PinkiePieJr's end. I've gone ahead and manually approved the request on their behalf. Your friends list should be updated accordingly.
There are a few reasons why we refrain from deleting member accounts:
Deleting an account would entail the removal of the member's topics, posts and blog entries. An action that could likely leave large gaps in the flow of conversations, or if the member happens to be the OP of a topic, potentially remove an entire thread. Generally, those who wish to have their accounts deleted, are the ones who end up returning at a later date. While this is not always the case, we've had members mark their return the the forums after weeks, months, or even over a year of absence. It's much simpler for us to leave inactive accounts intact, than it is for us to encounter a member who wishes to return after having their entire history here wiped. Most users wish to have their accounts deleted due to privacy concerns. Given that members are capable of changing all the information listed on their profile, in addition to their display name and log-in information, we are of the opinion that members are able to sufficiently cover their tracks if need be. It's also worth noting that we're often happy to oblige if a member wishes to have a specific post or thread of theirs removed due to personal matters (within reason of course). From an administrative perspective, it's of benefit for us to take a conservative approach to removing member content – you never know what information may be of use when dealing with issues in the future. I hope this clears things up for you.
It appears that you had the "Ignore all signatures when reading topics and personal messages" box checked under your ignore settings. I've unchecked it for you, so you should be able to view signatures of other members now.
