NEW MEMBER *BCIFU_MARIA IS **NOT ME!!

Some new person signed up 12 days ago, and named themselves bcifu_maria, for some odd reason yet to be determined. They took my I/D and name and combined it, I suppose to make people think its me?? The Account has also been being turned on/off, so it doesnt always come up. In the past myself as well a many others have had similar situations occur, and usually it would be done to falsely discredit me in some way. I have never seen anyone doing anything like this just to be nice to me or anyone else. Ive had one contact others and try to create trouble, but luckilly they quickly picked up on them.
If you hear from this person, please let me know. Any screenshots of all said would also be great.
I apologize to anyone this causes any unnecessary drama to in advance.
Thank You All, Maria
