So, I can relate to losing a bunch of effort sunk into the game due to someone else’s actions. That said, when you play a game on a server that shows a big pop-up message about how you should read the rules before playing on the server, maybe you really should get familiar with the rules.
In your case, what you did was pretty clear against the rules, as explained by Funcom.
“RP projects” like that are not welcome on official servers. There’s a post from Funcom staffer @Umborls clarifying certain things and giving examples of what you should not do on official servers. I would recommend reading all of it, but if you want to know how your RP project broke the rules, focus on the “Decorative Land Claim” section and the “Bridges, Roads, Paths” section.
Here’s a relevant quote straight from the rules:
That’s what you risk when you play on official servers.
Again, here’s a relevant quote from the rules:
Yeah, it would be great if they did have a warning system, but right now they don’t.
Long story short, while it does suck to lose all that effort, everything you needed to know was clearly spelled out and you could have avoided this situation by getting informed.
Unlike so many other cases, where it’s not always clear why the admins acted and there are suspicions of weaponized mass-reporting, this case is a clear-cut infraction of the rules.
