Sure, if you don't comment on Akismet enabled blogs you won't get blacklisted by Akismet. But you do realize you're still getting no backlinks from akismet enabled blogs, right?I do know that people run blog lists on non-existent domains a few times (and then immediately link check) so that they can be sure they have only extracted autoapproves to use.
If they then run only these on the domain, I think they'd be OK?
I think commenting on blogs with non-existent domains is ONLY USEFUL when you want to avoid heavily moderated blogs because heavily moderated blogs will not only mark your comment as spam (and your domain will get blacklisted by Akismet) but they will eventually report you to: Google, your hosting provider, your Internet provider and finally your domain company. :crazy:
