Luckily our website is not made by the same people as our infrastructure. This seems to be an overenthusiastic Recaptcha spam protection. I am going to make sure that it is fixed right away. (EDIT it’s fixed and it was caused by a Wordpress plugin that was not tested well enough).
Please take my word that this is NOT a good reflection of our technical skills (or lack thereof). My apologies for the confusion and inconvenience.
Short answers to your questions:
- Yes, Ghost can be configured as such.
- Images are uploaded to Discourse. You can “bring your own” S3 if you want. I would not worry too much about the sizes though. You need a lot of images to fill up space.
- From the top of my head, those comments are being cached for non-logged-in users.
- I’m afraid that would require a custom plugin, but that is certainly possible.
