Aren't all pens erasable with bleach though?

What matters isn't that the signature exists on paper, what matters is that you actually signed it.

No - pens with pigment based inks (the ones that were advertised heavily for being great for writing checks and signing documents securely with) will stick around until the bleach disintegrates the paper back into pulp.

The issue is mostly that it could erase by accident.
