:My only involvement in the matter is that I noticed that the sig had images, and I was dealing with the problem. According to WP:UNINVOLVED, "[a]n administrator who has interacted with an editor... purely in an administrative role, ... is not involved and is not prevented from acting in an administrative capacity in relation to that editor... Warnings, calm and reasonable discussion and explanation of those warnings, advice about community norms, and suggestions on possible wordings and approaches do not make an administrator 'involved'." This is the entire extent of my dealing with the user.
