The module should not require the user who is viewing the block to have access to the input filter. This check is only needed for users who edit blocks. Otherwise you might end up having to give anonymous users access to php-input.
Please look at block_block in API for a reference.

And I agree with the original post. Having to allow anonymous or any viewing user the "use" of a filter is a poor configuration. Someone posting a comment shouldn't see the suggested "gcal_events" filter in their input choices.
