Guild Wars 2

I’m sure everybody understands that, judging from the title, I’m referring to that little message which pops up saying “your message was suppressed due to excessive messaging.” Granted, the message is employed to genuinely stop spam from griefers and gold farmers, but over the past few months it has stopped at nothing to hinder my gaming experience, as well as my role playing experience. Just about 4 or 5 weeks ago it started blocking my say/map/emote chat, despite little messaging while role playing; and slightly changing the words made no difference. I often had to wait 15 minutes just to speak again, before being blocked yet again.
This is where it gets too frustrating:
I recently took a 3-4 week break from my pc, due to it getting repaired and me being on holidays, and today I decided to log on. I logged on one of my favorite characters with the intention to role play, but I decided to whisper “Hi” to somebody I knew. Apparently, that “Hi” via whisper chat was enough to set off a 15 minute block on map/say/emote chat, regardless of what I said in the following chat.

Is there any way to stop this? Or have I been reported or something? It’s gotten exponentially worse to the point that I can’t LFG nor role play at all, and it’s extremely frustrating.
