Framagroupes validation link

Hi!

I am trying to create an account on Framagroupes to manage an email discussion list. I request a first login and click on the link I receive via email.

But I always get the message

"Sorry, this operation can’t be performed
A validation link was sent to you on 09 Apr 2025 at 09:33:48. (the validation link was requested from host 209.93.193.105)

Reason
The validation link has already been validated from host 72.145.76.29. If you did not perform this validation, please report this confidentiality issue to your mail services administrator."

Who should I contact to resolve this?

Merci!
