Website looks clean, but the second disposable email address I tried showed up as "legitimate" while clearly being a disposable one. The service I tried with been online and active since at least 2018, so clearly not the problem of being too new. You might want to find new sourcing of domains flagged as disposable :)

Doesn't even flag the first result for "temp mail" on Google

> Why 0.1% false positives are acceptable: Disposable email signups are low-quality. A false positive means one legitimate user retries with a different address — a minor inconvenience. False negatives (letting disposables through) are the real problem, and bloom filters guarantee zero false negatives. this typical insane techbro considerations, would rather inconvenience REAL potential customers, than a TINY inconvenience for themselves for someone thats almost certainly not gonna be a customer. it is disgusting that anyone thinks like this, let alone spends the effort to implement it.

You've developed a tool to stop people from protecting themselves online. You should not be proud of it.
