A suspended account message is not always about you
A website can display an account-suspended notice referring to its hosting account. That wording alone does not tell you whether a personal login was suspended. Keep the exact address and message. This site does not provide a login recovery system for accounts on other Lekuluent-named domains.
Your list may be in another browser
Check where you created the list. A private window, another browser or another domain can have different storage. Returning to the original browser may reveal the saved choices. If website data was cleared, use a backup you made earlier; the site cannot reconstruct erased choices from an account that does not exist here.
Bring back what you saved
A Lekuluent list backup can be merged through My List. Open a restored title to confirm the details, then inspect any episode checkpoint. If you only remember a film from an older list, search its title and year and save it again. Read the backup steps before making further storage changes.
