There is a bug with the post editor. Images pasted from other websites from your clipboard will automatically use the [img] tag instead of uploading a copy as an attachment. Please manually save the image, upload it to the site, and then insert it as a thumbnail instead if you experience this.
Also this latest woke trend of self cancelling is monumentally dumb. (Well I say it’s a trend but there’s only that one Sonic site as well the Reddit co-founder so far that I know of, as well as this comic)
