Per [[https://commons.wikimedia.org/wiki/Commons:Village_pump/Proposals#Deactivate_cross-wiki_uploads_for_new_users|unanimous consensus at Commons]], users who are neither `confirmed` nor `autoconfirmed` nor above must be restricted from transferring uploads from one local wiki to Commons. In other words, IP editors (who are neither `confirmed` nor `autoconfirmed`) may be also restricted from using the tools.
[[ https://commons.wikimedia.org/wiki/Special:AbuseFilter/153 | Abuse filter was already made ]] at Commons to implement such restriction, but I can't help wonder whether it's adequate to prevent such users from misusing crosswiki tools. As I think, most (if not all) local wikis must also restrict such new users from misusing crosswiki tools
Per a [[https://commons.wikimedia.org/wiki/Commons:Village_pump/Archive/2024/06#A_new_research_report_on_Cross-wiki_uploads_have_been_published|study conducted by WMF]] ([[https://commons.wikimedia.org/wiki/File:English-Arabic-Cross-Wiki-Uploads-April2024.pdf|document]]), many uploads by new users tend to be eventually deleted primarily for copyright infringement and/or out of the project's scope, and many survey participants (new to uploading) were "marketers" or "self-promoters".
The implementation was discussed especially at Meta-wiki, but almost no replies have been made from what I've learned. Implicitly, no opposition or objection was raised.
**tl;dr** Besides Commons, most local wikis must also restrict non-(auto)`confirmed` editors (most likely especially IP users) from transferring uploads from local wiki to Commons. (Almost) no opposition to such implementation was raised at this time.
