There's no black and white solution, and the bottom line is that we trust our admins to use their discretion wisely to handle problematic situations. If someone is hanging out in the enemy spawn blowing them away repeatedly, that's obvious.
Setting up outside the spawn can go either way depending on the map, it's up to you to use your judgment on whether it's negatively impacting play, or sound tactical positioning. If nobody is able to get out of the spawn, tell them to back off. If there are other exits available, or the person outside the spawn is at significant risk of getting blown away, let it play out and only take action if the situation does not correct itself.
Do not go out of your way to find a situation to admin. That's not the point of being an admin. We're here to play and have a good time just like the pubs. The only difference is that when a situation arises, we're there to handle it. Anything beyond that is abuse and will not be tolerated.
