Website security blocking me from posting images to reviews.

I just posted my Suburbicon review, but upon first attempt I got a big intimidating screen to say I've been blocked from performing this action due to security concerns. Security provided by StackPath?

Anyway, I added my review again, first as blank text, then edited it to bring it closer to the way I intend it - first adding HTML for italics and bold, then adding a title (both worked), then for the edit purely to add pictures, I got the same security message again. So it's definitely related to adding pictures. Even adding just one picture triggers it. I tried adding different pics, but it didn't work.

Bottom line is, I cannot add pictures to my reviews right now because of this firewall.

Just an update to this. I tried again, and it turns out I CAN add SOME images... but only a certain length down from the review. I can't add images after the first paragraph, but I can after the second paragraph.

Mind looking into this one for me, Tom?

Until this is resolved, my workaround is to return to my former practise of putting quotes at the beginning of a review. It's something, I guess.
