Bug for Boards

This has happened to both me and ChaosReyn in the C&C boards, so it is hard to say if it applies to all boards or just the one.

We both had problems editing our own threads (meaning when we clicked save, something pops up saying it can't be saved). We both attempted repost, where it took us to a page with a big red X in the middle and at the bottom it says we are blocked by the website (LoL boards)

For my case, I was able to edit my old thread and save it after altering a few format. (Putting a space after using > for the box, skipping lines between ______, putting spaces between highlighted/italic words, etc.) It seems highly likely that something is wrong with the formatting (probably not on our end, but rather something with the boards' code).

I don't have any picture proof (forgot to screen shot xP because mind happened about a month ago, but ChaosReyn's case just happened yesterday and he is still trying to fix it).

Anyone knows why is this occuring? and how to prevent it from occuring
