I cant find griefing object on my land, please help.

[Rolo Scorpio]

I was going through and cleaning out my inventory a week ago and i came across an object the was named "ALL MY STUFF 50 K items". I rezzed the box on the ground at 2000m on a sky platform with nothing else around and it started spamming the local chat with "object owned by Rolo Scorpio is tracking Rolo Scorpio". As it was doing that, it started rezzing out little boxes all around me and each of them were the same size but had different amount of prim value ranging from 10-50 each. It used up all of the rest of the 750 available prims i had left to use on my land. I went and deleted all of the boxes that i could visually find and by using Ctrl+Alt+T for invisible prims. I cannot find anymore. It does seem that i have my available prims back to where they were but im not sure i got all of them deleted that i could see.  Now every so often when i teleport to my sim i recieve a message in my local chat saying .....

...... I do run a club and im afraid that it may be causing crashes and script errors on my land and its causing loss of traffic and buisness. Unfortunately i deleted the object from my inventory and in my trash along with my lost and found so i have not much more information on the object or pictures but i do remember it saying that the creator was a "Linden". Im guessing it is a fake name. I would like to just find the object that is still lingering around and get rid of it so i can continue my buisness without anymore messages sent to me about that object. If there is any help you can give, i would really appreciate it. Thank you.

 (P.S.) I have tried the answer below with "area search" and have found nothing with any of these object names :(

Have you already tried with a viewer with area search (Phoenix, Firestorm, Singularity, CoolVL...)? You can search for an object with a particular name - in your case "4" I think and locate it easily by double-clicking an item in the result list.
