Keep Rose. Add Targa.
You shouldn’t take a new tool’s word over a vetted one’s — so don’t. Add Targa next to your current bot: it starts in shadow mode, deletes nothing, bans nobody, and logs every action it would have taken with its reasoning. Read the log for a week, then decide on evidence from your own group.
Rose is a community manager with anti-spam. Combot is analytics with anti-spam. Targa is a security system — we match their protection, go deeper on detection, and skip the chat conveniences (for now).
Everything the vetted tools do
Switching — or running side by side — loses you nothing on the protection basics.

The zero-risk trial
| 1 · Add | Add @HeyTargaBot next to your current bot. It starts in shadow mode: nothing is deleted, nobody is banned. |
| 2 · Watch | For a week, every action Targa would have taken lands in the log with its /why reasoning. |
| 3 · Decide | Compare against what your current bot caught. Switch enforcement on — or run both forever; they don’t conflict. |
