Not entirely sure what your question is, but do realise that a journal needs to fulfil certain requirements/criteria to be included in Scopus: https://www.elsevier.com/solutions/scopus/how-scopus-works/content/content-policy-and-selection In order to keep their indexing a journal is subjected to re-evaluation as well I quote: “To determine journal quality, Scopus runs the ongoing Re-evaluation program which identifies outlier and underperforming journals in four different ways:
1 The journal is underperforming as it does not meet any of the three metrics and benchmarks for journals in the same subject area.
2 Concerns about the publication standards of the journal or publisher have been raised by formal complaints.
3 The journal shows outlier behavior based on its publishing performance in Scopus.
4 Continuous curation based on CSAB feedback.”
See the above link for more details. Point one and three is a frequent reason to discontinue a journal when the journal all of sudden accepts more papers compared to their history. Point 2 is often found for so-called predatory journals (or publishers behind those journals) when it comes to proper peer-review and plagiarism.
Scopus frequently publish a list of discontinued titles (see enclosed file), see also the following discussion for those interested: https://www.researchgate.net/post/Is_Scopus_doing_a_good_job_in_identifying_and_dealing_with_predatory_journals
Scopus subjects its indexed journals to a regular review to examine them according to certain publication quality and standards. It removes a journal if it derails from the agreed-upon criteria of selection and inclusion, such as journal policy, content quality, journal standing, regularity, and online availability (see FAQs attached). The following could render relevant insights.

Hi Dr Ibrahim Alrashid . The quality of journals indexed in Scopus is reviewed at regular intervals or when publication concerns are raised. If a journal is found to fall below a specified standard, or the publication concerns are valid, the journal may be removed from the database.
