The former seems more polite, sensible, and just generally respectable, so one might assume that it is the organisation.
The latter is puerile, insolent, and as foul-mouthed as a 16 year-old, so that seems like the 16 year-old.

However, upon further investigations one can deduce the former is a small group and the latter is more substantial, which leads me to think that the Pro-Test is the 16 year-old boy, but is sensible, rational, and mature whilst the SPEAK is a group of immature people with nothing better to do than slander a 16 year-old boy.
