Left a comment on Heather's 'telltale NOW' blog yesterday morning. It was gone by the afternoon. Then I left a comment saying that it was odd that the first comment was removed (nothing offensive / controvercial in 1st comment that would give any cause for removal, just a comment and link back to a similar themed blog from a few years ago "To Rule is Cool' that was inspired by a comment I made about getting comfortable and losing one's 'edginess'). The 2nd comment is now gone too.
If the comments are being manually removed, fine, though a little heavy handed and out of character for Telltale mods.
And if they're not being manually removed, you might like to take a look into the glitch that's making them disappear.
