Posts can be deleted but I wouldn't. You can pin a comment with the links fixed if you're logged in as the OP though.

To pin a comment, click on `...` in a direct reply and you should see `pin item` as an option.

Can posts be deleted? Should I re-upload? There are a lot of links...

Yes, there are [different flavors of markdown](https://gist.github.com/vimtaai/99f8c89e7d3d02a362117284684baa0f). We use [Github Markdown](https://guides.github.com/features/mastering-markdown/) and we don't use the non-standard `tab:` prefix to mark that the link should open in a new tab. Every markdown link opens in a new tab on SN by default.
