Please explain why

[dot.hawkes]

my dot.hawkes ID has been suspended within the last few minutes.
My posting pattern tonight has comprised of the following;

post at 20;49
double post at 20:53 and 20:54 on wqardy's thread
post at 21:15
post at 21:21
post on same thread at 21:25;21:31;21:35;21:4821:52
and final post that didn;t get thru at 22:08.

What AB rule have I come up against to warrant a sudden and unnotified suspension?
