Your character makes a reputation for themselves through several means.
- Their own actions. Do or say something people don't like or find objectionable? You're damn right it's going to stick with you for a while.
- People they associate with, which includes corpmates. Hang around people with bad reputations, and you'll get a rep for doing just that - and subsequently for clearly not objecting to their reputation/actions to the point where you would not hang out with them.
- Their corporation history. Join a corporation, and you pick up its baggage. Your corporation will have its own reputation based on the collective actions of its members. What they do, will affect your own reputation, for better or for worse.
- Their allies and enemies. Who you fly with or against will reflect on you and your corporation.
In this case, Streya is in a corporation that has had, well, not the most stellar history IC. Its CEO has done some pretty weird things that people didn't like, and it can say something about people who will willingly associate with someone who's done things like what Saede's done. You're blued with TS-F (or were, at one point) and come across as, in many ways, "Nation Lite™".
Now you're espousing Star Fraction-esque philosophy, rhetoric and methods on the IGS. And attacking another corporation on grounds that appear diametrically opposite to previous stances given by your corporation. A corporation with a pretty solid reputation of its own that is well-known for being primarily made up of frigate specialists, and not very good targets for your chosen type of warfare.
You've made your bed IC, and now unfortunately Streya needs to sleep in it.
All of these are perfectly valid reasons for people to leap down your throat on the IGS, whether they're friends of Pyre Falcon or not. Some will do it because Star Fraction is a heavily polarizing group and subject even years down the line (and people emulating them WILL evoke reactions from people as a result). Some will do it because you're Nation Lite™. Some will do it because you're attacking friends. Some will do it because you're making yourselves look incompetent in various ways. And some will do it because it's a damned trainwreck waiting to happen, and human nature is to watch and gibber about potential disasters-in-progress with awe and fascination. Sure, there might be some 'circle-jerk' to it, but I think there's a lot less of it in this particular case than some are suggesting there is.
