Persistent Wancelibbe.Club Pop-Up Notification on iPhone

It has been going for about a year now and pops up unpredictably, it even can “stack” and I have to close out of it twice. I could also have my phone off, I would go unlock it and I would get the pop up as well. I haven’t seen much anywhere else, I can’t find a website as to what it is and the details don’t provide any useful information.
