The problem using too much def will cause the exhaust to clog up over time

Excessive particulates will clog the exhaust, but I don't see how excessive fluid will. Are you sure you not mixing up between DPF and DEF.

I'm sure... The particulates I'm referring to is the DEF crystallization that will form in the exhaust when too much is applied.

I didn't think about this but it makes perfect sense. Thanks for the link.
