Hi, so I was thinking about this, and the only reason I could see that at signs would be replaced with this (A-T) string is that in case someone puts their email out there in a topic publicly and spam bots could pick it up and do their spam bot thing. If that's the case, I can tell you that even in this case, if whoever created this bot took some time about it, they could counter these permutations by using regular expressions to search out anything that could be an email address
OK so, I'll use atsign to refer to shift 2 in this example because sometimes the transformation happens, other times not so its hard to repeat, but if my email is honeybunny5atsigngmail.com and we change it to honeybunny5(A-T)gmail.com something like the following would find it:
OK, so that's sloppy, and regex are not my best strength, maybe someone can come up with an example, I didn't even test that one to see if it worked or not, but the point is, its easily reversible, and a bit of a nuisance on our end to be seeing (A-T), so can we maybe get that lifted.
