Considering selling my $240 MRR AI app: killspam, has 3 paying customers

I'm considering selling my AI app: https://killspam.app, it has 3 paying customers. $240 MRR.

All 3 customers are YouTubers with >200K subscribers.

Been running for a year without promo. I've just rewrote backend, running cost now ~$50/mo.

Anyone want to buy it?
