Description

Background

Blocking an IP address blocks temporary accounts from editing from that IP address, and as a result blocks new temporary account creations.

This is not always known to users who perform blocks, but could be explained on Special:Block.

It is also helpful to understand when there are multiple temporary accounts using an IP. This information could be made more available too, and a link provided to Special:IPContributions.

Acceptance criteria

When entering an IP address/range target into Special:Block, text appears beneath the target field: All temporary account edits from this IP will be blocked. Temporary account creation from this IP will also be blocked.
A link to Special:IPContributions for the target is also shown

When entering an IP address/range target into Special:Block, text appears beneath the target field: All temporary account edits from this IP will be blocked. Temporary account creation from this IP will also be blocked.

This is done in the patch above (in core).

This needs to be done from CheckUser.

@Tchanders is it possible to include the number of temp accounts on the IP/range too?

Re-opening this, for adding the IPContributions link from CheckUser.

For this we'd need to do an API request for the number of IPs, because the IP can change dynamically as the user changes the value of the target input. We don't currently have an API for looking up the number of temp accounts without looking up the actual temp accounts, which would cause the same logging problem as T412221.

But it's worth filing as a separate task, so we can decide if it's worth adding this API.

Should we localize the special page name in this message on the UI?

[[{{#special:IPContributions/$1}}]] should do I guess?

Perhaps we could just use a piped link to "conceal" the special page name, because such magic words can be parsed only in PHP modules and not in JS modules.
