I am trying to run a search that would return first names that are random string of letters/numbers. We had a lot of spam come through a signup form, where first names look like "sldkfmVUnkdUnnns" or any other random string of letters. I was hoping I can use search kit to find first names that are longer than normal? I tried to use "matches pattern" but I'm not sure what to do.
Does anyone have a good solution for finding these spam records?
