*Abuses powers to post in closed thread*
It's very difficult to say whether any given act was accidental or deliberate. Anyone can "accidentally" post something they shouldn't, and say they didn't intend to do it.
However, if policy changes and people are allowed a "second chance" for accidental posting of pornography/inappropriate imagery, then we're sending a message that it's quite all right to post it, provided it's only done once. Anyone with a chip on his or her shoulder could "inadvertently" post something objectionable and expect to get away with it. If PeTerL90 is unbanned, then anyone else banned for pronography could simply say, "I never posted that on purpose, you've got to unban me or else that proves you're biased and hypocritical because PeTerL90 got unbanned."
This would simply be unacceptable.
The fact that Bert avoided a ban is unfortunate; however, only one Staffer was present at the time, and she dealt with the matter as best she could under difficult circumstances. We can't all be everywhere at once. One inadvertent oversight by one of our best and most-respected Staffers in no way justifies a sweeping policy change on a problematic topic like pornography, in my opinion.
