I've agreed and disagreed to some of your points. Just pointing out why it's not too much of a big deal in the end and how you can maturely deal with the advertisers, especially the ones that choose to do it in the novice network. You stated that it ruins your experience with the game. Which is a bit over the top, since you're the one who's making it out to be a problem more than it actually is. It's annoying, yeah. Really annoying if you have no interest partaking any part in it. But it shouldn't ruin your experience if you choose to ignore it when it gets advertised at main city hubs. It's a community thing. Most people ignore it if they're not interested. The curious players (who are likely new to the game and have not explored that aspect of FFXIV yet), are likely going to go there and probably develop an interest in the RP scene.
You are such a little snowflake. It's rather amusing. So are people suppose to blindly agree with you without giving you a more broad perspective on the matter? And yet I get called manipulative when I disagree with the point of you wanting the developers to do something that could be absoolutely detrimental to the RP community. You go as far to say that you don't want them in your PF now, but do you know how hard that will be for a newcomer of RP who wants to partake in the activities? A huge majority of casual RPers do not rely on discord, they just like browsing the PF to start venue surfing. Oh, but you don't care about those players, you care more about yourself and want to push your selfish agendas among to others.
Although, I can guarantee you making a post about this is pointless, because nothing will be done about it in the end. They're not going to ban the advertisements. Which is why I informed you to not let the advertisements get to you, because your problem won't get fixed. You're lingering onto this issue that it is your fault that it's a bigger problem than you make it out to be. FFXIV is a very community driven game, so let it continue to strive in that biggest strength it has against other MMORPGs.
