Indexed, though blocked by robots.txt

Google Search Console was warning me:
Coverage > Indexed, though blocked by robots.txt

Affected pages: 1.57K
The number of warnings has increased significantly recently. Google probably changed a policy.

The warnings are mostly for things like:
https://www.scubadoctor.com.au/diveshop/index.php?main_page=popup_image&pID=4896
https://www.scubadoctor.com.au/diveshop/index.php?main_page=popup_image_additional&pID=4612&pic=2&products_image_large_additional=images/ocean-design/ocean-design-moana-msf-pkg_03.jpg
https://www.scubadoctor.com.au/diveshop/index.php?main_page=product_reviews_write&products_id=5691

I can see why it might be useful to let it index the additional images. So I changed my robots.txt file.

Instead of just…
Disallow: /diveshop/index.php?main_page=popup_image*

I now have…
Allow: /diveshop/index.php?main_page=popup_image&pID=*
Allow: /diveshop/index.php?main_page=popup_image_additional*
Disallow: /diveshop/index.php?main_page=popup_image*

That worked.

Google is still insisting that it wants to index pages like
https://www.scubadoctor.com.au/diveshop/index.php?main_page=product_reviews_write&products_id=5692
even though they're blocked by robots.txt

I can't see any reason to allow product_reviews_write pages to be indexed. It's meaningless to index them. It's pointless given the bot and user will just see a login page.

On each product page there are two links in the reviews section like this.

The plan is to add rel="noindex" to those two links. Then maybe Google will get the message and stop complaining.

It should already be setting noindex,nofollow on those pages, as per:

Right, but that's on the page itself ... not on the associated link to that page.

The bot will never get to the product_reviews_write pages to see the meta tags there. It will be taken to a login page and get no further.

The login page has
<meta name="robots" content="noindex, nofollow" />

Yet still Google insists it doesn't want to be blocked.
