Possibility for new blocking/auto-decline options?

I recently got bored on my main server and created a new character on a new/random server to play by myself when I was bored. I must say, I have never had so much fun playing by myself without joining a single linkshell or free company.

However, not having joined one since my initial character creation has been very irritating and frustrating. The other day, I had the same FC shoot out about 20 invites throughout the same day as if they wouldn't take no for an answer. I contacted their FC master to ask them to stop but he never replied back and the invites continued.

I am looking for more of an option that lets you block other things, like party/fc/ls invites. Wanting to play alone, having an auto-decline or auto-block option for these invites would be great to have. Thanks for taking the time to read/comment!
