Finally a Solution for Base Attack Problem

[Lemon]

I don't see the issue - why do you have to exclude indies at all? What's this need for elitism in defending PoBs when you could just win by numbers and get more PvP action to everyone? There are now multiple repair ship freelancers for one you could have just paid.
And I assume all metagaming siegers know there is a discord group that has a bot that pings every time there is a siege anyways

Let indies in, advertise it openly on the forums and in external servers, and have a locked hashtag for only people you trust but ping the open one every time there's a siege and bot pings attack message. This will be good for everybody

Yes, because information like what your composition and tactics are going to be should be guaranteed public information, and not the result of one particular person being particularly scummy.

Not sure if you are a beginner or are pulling my leg, but in discord you can restrict hashtags and just ping indies when you need them without revealing specifics to them
