comment Data structures and algorithms for a directed rooted tree with inherited properties?
Are you open to using multiple threads? It is easy to make all operations fast if your operations update information and invalidate some caches. And then you can have a background process fixing up the cache. Searches will usually be fast, unless cache is not rebuilt in which case they won't be slower than they would otherwise be.

comment Notifications system with too many subscribers
@php_nub_qq Well no, it is not straightforward. You could also have an email notification system that sends things immediately. In that case you have no need to even store this data in a table!

comment Duplicate Account Detection - New Approach?
The idea is to keep cheaters from knowing what they were caught by.

comment Duplicate Account Detection - New Approach?
The solution to THAT is to make cheating detection soft, and then occasionally get a bunch of accounts.

comment Duplicate Account Detection - New Approach?
You will catch duplicate accounts for banks, but not ones created to spy on other alliances. You will also misidentify farms as being duplicate accounts when they are merely regular victims. The bigger question is why duplicate accounts actually need to be prevented. If you look closely, the people who do it are probably your best potential customers. Why not take advantage of that?

comment Should a developer refuse to access production server?
@Disco3 This does come up. But that is where, "Measure twice" comes in. Try to figure it out, and only after getting blocked say, "I can't."

comment Is “friendly fire” session replay a valid concern?
@MSalters I disbelieve. The overhead of checking session time relative to everything else is pretty small. If that straw breaks the camel's back, the back would break soon from something else. And besides, everything on the server side should be designed to distribute across machines. Then server load is easy to scale.
