NamelessMC is website software for Minecraft servers. In version 2.2.4, core/classes/Misc/ProfilePostReactionContext.php only verifies that the wall post exists and does not enforce blocked/private-profile visibility. This means that authenticated low-privileged users can add reactions to private or blocking profile posts. Version 2.2.5 contains a patch.
