You know, when it comes to Honkai, does it really deserve a look-alike since Hoyo is known for having expies? I feel like explicit expies should be a separate tag while look-alikes should be reserved for unrelated IPs

Look-alike is our tag encompassing that. The only thing that creating a separate tag for that case would do is fracture the tagging for other look-alike scenarios and make it confusing for people who don't know the specific reason. People should be able to find post #10871587 and post #11337763 all under one tag search.
