Free Company invite spam

My brother and I play on Alexander server. For about a week now, we've both been getting random invites to join a Free Company called "1st Class Soldiers". We decline it every time, and about an hour or 2 later, they send us another one. I finally grew tired of it and accepted the invitation, just so I could tell them to stop sending us this spam or I would report them for harrassment. After I quickly quit the FC, their leader, one Zain Kurai, whispered me saying that I was the one harrassing them.

Please Square-Enix, add an option to automatically decline Free Company invitations, or at least let us identify the ones making these invites so we can blacklist them if they're being annoyingly persistent.

Oh, and before I left that FC, I saw that they only had 20 members. If that's how they recruit people, then it's no wonder they're so small.

For the sake of accuracy and truthfulness, these are the exact words I said to them:

"you people are b*******, and you need to stop spamming invites at me, or i will report you for harrassment"

Zain Kurai's reponse: "so you join just harrass, and threaten over 20 people online?"

If anyone needs further proof, I have a screenshot of the chat log and will upload it if necessary.

I have been seeing this and also blind FATE invites. Both insanely annoying.
