I'm sure someone has asked this in the past, however I couldn't find a thread on it, so I figured I'd ask it. My question is this: How Do You Stop 2 Different People from Registering For An Event With The Same Email Address?
We get a lot of people who register for our live events who also register a co-worker and they end up using their email address for both. So for example, John & Jeff want to attend. John registers himself using email@example.com. He then registers his co-worker Jeff and uses John@awesomeco.com. We've noticed that Marketo will override John's name and place Jeff's name in the reg list and in Marketo. So not only will John not show up as being registered anymore but also his name in the DB will be overwritten. We want to stop this. Has anyone else figured out a way to pro-actively stop this from happening?
