Limit Sign-Ups per IP Address
Allows only a few new accounts per IP address per day, which stops bots and people from creating piles of accounts.

Restricts the block widget editor and the Customizer to a short list of blocks that make sense in sidebars, keeping widget areas tidy for clients.
Limit the CSS Units Offered in the Editor
Reduces the unit dropdowns in spacing and size controls to the units you want (for example px, rem and %), keeping layouts consistent.
Limit the Embed Providers in the Inserter
Hides the long list of embed blocks (TikTok, Reddit, Kickstarter and dozens more) from the inserter, keeping only the providers you actually use.
Limit the Maximum Upload Size
Caps the size of files that can be uploaded through WordPress at 8 MB, even if the server allows more.

Stops shoppers from adding more than a set total number of items to the cart, for limited releases or stock-controlled drops.

Refuses to send any single email to more than a set number of recipients across To, CC and BCC, which stops a compromised form or plugin from blasting your contacts.
Limit the Number of Tags per Post
Keeps only the first few tags on each post when it is saved, so tag lists stay focused and tag archives do not fill with one-off tags. Writers see a note when extra tags are dropped.
