Help please.

The player was using mob disguise (Which is a donator command ). As for the the force tp, only moderators + have force teleport so he found your base legitimately. That or you or someone else accepted a tpa request.

Hello. Around 18:00-18:30 (central europe time) i was at my house doing stuff. Then i hear my doors opening (pressure plates on the inside, nothing outside). I was far from these pressure plates and there was no way i opened them. Now i am asking you,moderators and admins, if you teleported to me while invisible to check out what i was doing (that's fine) . If not,please tell me if players with force teleport command are allowed to use it on others. I am asking because after like 2 minutes, i noticed a rather unique cow, scouting my house. I chased it, and it turned out to be an "Elite" player.
Please answer my previous question. If this really is an abuse,i will provide more informations about him.
Edit: My house is extremely isolated from the rest of the world.
