I'm assuming it still works, as I haven't logged in lately to try it, but if you go into your options menu, into the chat settings, you will find a box where you can input someone's username, and you can blacklist them that way. Pretty sure it'll hide their party ads! I'd like to know if someone can test this, I don't have time to login right at this moment to check.
Whether it's a glitch or mod is frankly irrelevant, point being I don't want to be seeing messages spammed over and over and have no way to block it.
I mean you're kind of doing it again? Saying things before doing your research. You can block the messages by pressing enter and switch over to the normal chat tab so you ignore party advertisements.
Disclaimer/Off-Topic : The research/analysis that I have done leaves me to conclude that all of those so-called «natural-disasters» are not from so-called «climate-change» nor «human-production of CO₂», but, rather, from literal weather-control technology/weaponry that's been weaponised, for which literal patents exist which detail how to «control the weather» and the fact that there's even a literal document from the «military» itself, open and available to the general public, with the name/title... Owning the Weather by 2025
I think the idea of a reconnect function kills the game. There is no fun in playing a game that does not punish the player. For example, back when players died, unblessed equipment had a chance to drop on the ground and you would have to pay for that gear back at the town. This game needs more punishments, rather than catering it to sheltered children.
You should move. Mabinogi is not your excuse to stay in the middle of nowhere.
