I just figured out that depending on how you enter the portal you land beside the portal, so death is certain. Saying that, your portal is a at least so insecure that you had to change the design.

Interesting to see that staff allows players to build something like that.

When passing through a nether portal, you do not 'land beside' it. You land ON the portal frame. Where you go from there is completely your choice, action and responsibility.

Staff take action if and when that choice is taken away from players. That might be via blocking in a portal which results in them being stuck without the ability to even chat or issue commands, or it might be via luring someone into a death trap under false pretences. Whoever it was that died in this instance HAD choice about their actions, and it was their choice / lack of care in stepping off the portal frame that resulted in their death. Their choice therefore their responsibility.
