Only Oversighters can delete a abusefilter logentry. That's an problem, because you have more stric criterias for deleting an entry. For example: A copyright violation at an abuselog entry should be deleted, but this is not a suppress criteria (at the most cases), so this entry will not be suppressed, it's mostly public visible.
Create a two steps system, like at revision deletion:
- Sysops can hide an entry
- Oversighters can suppress it
Current hidden entrys would remain as suppressed.
