With AH I use same for now, until I get my own front for it

It’s bad OPSEC doing that

Only if I want attribution of some sort to that LNUrl

All my bots have the same address for receiving zaps

I would keep them separate

The only other npub I am still using, outside of those I use only for testing purposes, I use a separate lightning address and zapping wallet with.

Using the same NWC connection and lightning address on more than one profile seems to work fine.

I use a different want for send and receiving on each account

I mess around with this quite often. At the moment I am using my main nym primal wallet for both Damus and Primal to send and receive. I was using it over at Olas too but have switched to my test nym (and its NWC primal wallet for that). Before that, I was using coinos wallet for Damus to send and primal wallet to receive and then exclusively coinos to do both.
