Competitors mentioned: disposable/disposable GitHub library, Gmail, ProtonMail
Concerns raised: Blocks legitimate users while hackers easily bypass with new email providers, False positives inconvenience real customers more than false negatives harm the service, Misses active disposable email services that have been online for years, Can't realistically block all disposable emails without blocking major providers, Punishes users seeking privacy/anonymity rather than solving actual security problem
Feature requests: Improve disposable email domain detection sources, Add regression tests for recently discovered disposable services, Support custom/adhoc blocklists in addition to primary list
