Lizzy O'Shea of Digital Rights Watch is acting as Alliance for a Safe and Secure Internet,
Erm, I'm getting cognitive dissonance there. You've introduced the "Alliance for a Safe and Secure Internet" as having a lot of big and important members behind it (oo-er, missus), now you imply she's one woman.
I can correct that in various ways, with meanings that are similar but not identical:
" ... is acting for ... " (the minimal correction in letters changed)
" ... is acting as spokesman for ... " (as above, more specific capacity)
" ... is speaking for ... " (limiting the occasion too)
" ... acts for ... " (generalises the context),
" ... speaks on behalf of ... " (generalise context, specifies capacity)
etc.
