Description

For example a user be indef blocked twice.

AbuseFilter may automatically issue block, and if talk page access is not revoked, new blocks can be issued even if the user is blocked (by abusefilter or others).
User may deliberately generate a large number of abusefilter blocks, and if the number of blocks on one user is unlimited (cf T351508: Decide the limit of multiblocks), potentially we may run into performance issues.
This will be more a problem once T201815: Implement partial blocks in AbuseFilter as they'll be available is resolved.
