If the new players who enter the server after the seeker hole is created are affected by it, then I suppose a server-ran program to eliminate the "seeker magnet" would also stop the seeker magnet from effecting players that join the server after it was created. However, if it doesn't, that's good. If there was a program to be created, I would assume that it would have to be ran by the clients or just the server running it would work. I'm not completely sure about this, but the clients of a server seem to take almost every setting from the server. Wouldn't this include seeker magnets? If so, a program just running on the server could eliminate that, right?

Correct me if I'm wrong, which I likely am. This isn't an area I have much knowledge of at all.
