For weeks now I've been getting party invites from obvious bot characters (nonsense names like Bababsbhjs and not replying to any messages) on all of my characters. I'll put them in ignore and that would help for a day or two land then I'll just start getting invites from a new bot character. The one time I accepted the invite to see what they want it was a big raid group full of offline people. They never reply when I ask what they want. What's going on here?
I think those were advertisers. I am getting the invite for like 2+ weeks now. Whenever join my other toons, I am getting same invitation. That's why I know.
Last(or more) week, it was 1 level toon. And after that, it changed it to 10 level toon.
This bot changing name everyday or so. And probably have huge list of player or spamming 'who' to get list of people. And invite them.
And advertising their website--or game coins. I joined one time long time ago so it might be other person or bots.
