Subscribe links in comments even when subscription to content type is blocked

The title says all :)

Seriously, is my setup:

I have set up subscription forms to display on separate pages. I want users to subscribe to 'Forum', but not to 'Blog'.
When an authenticated user visits a Forum node, he sees the 'Subscribe' link under the node, and under each single comment. That is redundant, but is ok.

But when a user visits a Blog node, he does NOT see the link under the node, which is ok, but he sees it under each comment, which is NOT ok, since the link brings to a page where the user can do nothing.

I fixed this changing line 67 in subscriptions_ui.module form this:
if (subscriptions_ui_can_subscribe() && empty($teaser)) {
to this:
if ($type != 'comment' && subscriptions_ui_can_subscribe() && empty($teaser)) {

This solution is ok for me because I don't want the subscribe link to be repeated under each comment, but this could be made optional.
