The censoring of the email address looks terrible. It looks like someone has just drawn a line over each email in paint. I would not be surprised if the original email could be recovered just by putting the different "erased" copies together.
Edit: Got the above by combining emails censored in the top part of the first screenshot. You can definitely reveal the full email if you incorporate the other screenshots.
Tossed into photoshop and just put all versions over each other w/ darken layer...
Looks like zoparlek@thiessen.org but theres a few characters that look a bit iffy.
