Thanks Jazzgirl. The problem was that the heading wasn’t 100 characters but the system suddenly thought it was because of the extra coding that popped in.
I remember the Korean spam, Ash had to ban loads of characters. It caused an enormous problem because it banned unexpected things. For instance, some dashes were banned but not all, it all depended on how the individual computers read the coding for the characters.
It solved the problem though, they never managed to return.
