Who wants the red X back?
I would assume the red x went away because somme lurkers have been going through old threads and red x'ing them long after they are inactive.
I was looking for a thread I had hit the "like" button on a while back and noticed someone had gone through 60+ old threads/replies and red x'd them. I didn't recognize the username and just moved on. At the time I fogured it was somebody trying to male trouble with a second account. These people I tell you ... way too much spare time lol.
