Disabling endermen from picking up blocks

[Bullzeye2448]

Hello, I've had a server for a few of my friends for a few weeks and our spawn area looks like swiss cheese from all the endermen. Yes, I have already deleted any and all rifts and doors near the area and would just like to make sure they stop griefing the landscape permanently. I've tried adding some plugins but they don't seem to work or I must be doing it wrong. Any assistance on this matter would be much appreciated. Thanks in advance.
