What, if anything, are teams doing to help counteract customers that may be using temp email addresses to sign up multiple times for welcome coupon codes or offers? We ran into this recently and found a customer has been doing this periodically for about a year. I know there are many sites out there that give the email addresses (maildrop.cc, ohmyfly.com, etc) and this may be a somewhat frustrating exercise, but has this come up for you?

We have a suggestion from the support team to add a filter to the beginning of our welcome flow with the offending domains and kick them out when they are identified - and we probably need to make sure they are added to a "to delete" list to dump out the bad ones periodically. I've also reached out to our CSM to see if anyone has compiled a list of these types of domains previously otherwise I will dive into the web to see how many I can identify and filter for.

Anyway - just thought I would ask if anyone else has had to deal with this. Happy Friday!
