In house pride, it's the other team that will probably report you (as it is the house with the most points that wins, not the individual person).
Normally, people would only be 100-200 points ahead if they had saved up house points ready for a house pride (i.e Dumbledore at the end of year 1,2,3 etc...). Fortunately for you there's a TLSQ on at the moment which gives a lot of house points, which means that it will probably look more natural for someone to be slightly further ahead if they have completed it.
To be safe, don't earn any more house points. While there is still a high-ish chance of a ban if the other teams get jealous, you might get "lucky" and 2nd place will catch up or another team will overtake you.
