bl_by_actor
editActor who made the block.
bl_reason_id
editKey to comment_id. Text comment made by blocker.
bl_timestamp
editCreation (or refresh) date in standard YMDHMS form. IP blocks expire automatically.
bl_anon_only
editIf set to 1, block applies only to logged-out users and temporary users.
bl_create_account
editBlock prevents account creation from matching IP addresses
bl_enable_autoblock
editBlock triggers autoblocks
bl_expiry
editTime at which the block will expire. May be "infinity"
bl_deleted
editIf true
, this block causes the username to be hidden, and the expiry must be infinite.

bl_block_email
editBlock prevents user from accessing Special:Emailuser
bl_allow_usertalk
