I realised this morning that over the weekend our duplicate contacts had increased by 2000. Has anyone had this happen before or know what may have caused it.
Thanks 
So far the person on chat didnt know either…
Hi @KMcLean3,
Thank you for asking the Community!
I understand that duplicated contacts increased in your portal.
1. Have you done an import of contacts recently?
2. Is there any updates that you made that could have caused this? A workflow? A third-party integration?
The more info, screenshots (without sensitive/confidential information), and details you can provide, the better the Community can assist.
I’d like to invite a couple of subject matter experts to this conversation: Hi @karstenkoehler, @Bryantworks and @beeginman do you have suggestions to help @KMcLean3, please?
If anybody else has anything to add and/or share, please feel free to join in the conversation
Thanks a lot and have a great day!
Best,
Bérangère
Hi @KMcLean3,
That sounds familiar 
I was missing control over our duplicates so we developed a HubSpot plugin to tackle this. The plugin adds properties so you can create views or reports of duplicates and highlight the recently created duplicates. You can start a free trial to find out what happened in your instance!
Hope this helps!
