I've seen Pepperstone do similar, generally with exotics as well, although there is another thread on here where a guy was filled on GbpUsd 10 pips above the high of the bar on the news the other day and it wasn't even that big a news release.
Quite possibly genuine in what's happening but it's very damaging to accounts. I'm currently not trading with Pepperstone for this exact reason.
