Alright, after another user pointed it out to me, I suspect the reason you aren’t seeing links to the modlog is likely because you were on piefed.world. They have been slow to update their piefed instance and are still on the 1.1 version. That means that updates to piefed that have been introduced in 1.2 (current stable version) and 1.3 (current dev version) are not present. Some updates to the modlog since then:

• (1.2) searching and filtering the modlog if you are logged in
• (1.3) introducing a dedicated link to the modlog on the footer of every page
• (1.3) adding a link to the modlog on each community’s sidebar
• (1.3) adding a link to the modlog on a user’s profile page
