Great question. I think the biggest challenge would be maintaining high-quality reports/complaints. Basically, preventing people from reporting things that they opted in to but are frustrated with (just because it's really easy to do). There's a chance that the reports would actually become worse (less actionable) if it was too easy or too automated.
A small challenge is that the high-quality carrier lookup APIs charge a fee for each query. The fee is tiny (like 1/10th of a cent per number), but enough to add up.
