Virtual Service Agent is an “anti-non-decoder” code gate, as Wraparound is an “anti-non-fracter” barrier (both being cheap NBN ice). While the latter just asks you to have some fracter, the former asks you to use (and reuse) the decoder you have. So if you don't keep buzzsawing VSA fair and square, you'll keep taking 1 tag
(and losing $1
too).
Because VSA forces them to take the tag, which can be more valuable depending on the board state. Authenticator always gives the Runner a choice on whether or not to take the tag, so they'll only take it when it's advantageous for them.

Why? Why everybody plays this card unstead of authentificator? It dont have pseudo etr. It cost 1 to break after Runner put decoder (instead of 2-3). It is fragile to chisel. It is expensive pop up window, nothing more
