I discovered this after twice having my post eaten which contained the string: 70 < X < 80.
Obviously I'm typing the HTML code here because I can't type < without the rest of the post getting culled. This very much sounds like bad use of HTML code detection.
Even the "insert code block" option barfs on the usage of this bracket!
