This reasoning is incorrect, and I'm sad that I have to debate to undo this match's removal for a second time. The first time removal was discussed (for the 3-D plothax reason you gave below) was
back here (damn I was way too hostile back there, sorry Zach).
Being able to act in a place without a script does not mean you are immune to all plot-based abilities. While the script was there, Monika was still very clearly bound by it, she was unable to hang out with the player too much while the script was still up. Sometimes the game would fade out while she was trying to talk to you. Other times she'd complain about how it seems to be a law of this world that you always end up dating other girls and can never date her.
So, the match should be reinstated.
Now that I think, 3143's Plot hax is 3-D, Monika's is 4-D due of the plot being also across space and time, as erasing a character from plot erases them from the space time as well. Screw it, Monika completely stomps 3143.
What do you mean his plot hax is 3-D? Where did you get Monika's plot being across time but 3143's not being such? He brings those he "flattens" into a narrative under of his own which lasts for a period of time before being applied to reality. 3143 resisted the same sort of EE. Monika does not stomp.
Thank you Riki for suggesting I should be contacted, but only pings from staff members give notifications. Someone should have told me about this on my wall so I didn't need to see this in my list of followed pages and ask Starter about it to find where tf it came from.
