Guild Wars 2

Here is the scenerio – 2 days running ive been doing the champ zerg in queensdale (sorrows furnace) – no problem.When players asked where zerg was i was saying for them to “join me for zerg” , along with me chatting as normal suddenly the next time i put in join me i got message supression.
Weird i thought as i wasnt exactly spamming chat.
Yesterday i was announcing the next wp for new players as well as chatting on an off – yes the message supression kicked in after 3 wp`s and i ended up with 3 new players standing next to me because i wasnt able to speak at all.
This has happened only since 2 days ago , its not a case of spamming the wp`s too fast as a good example would be the time between spider wp and waiting for boar which is say 5 mins and i could be silent for those 5 mins ( no supression ) but add phiney wp in chat and supression kicks in.
Has anyone else experienced this – i dont really want to send anet a ticket with a load of pics etc if its only me , btw i redid the data file so its new.
