My opinion, Donari, suck it up and get over it. If a guild does not like you IC, they can tell their guild IC to not interact with you. For you to try and stop them doing so is, for lack of a better word, godmodding. You cannot enforce who RP's behind your back, what IC rumours they spread, and what they IC things they as a guild do. That is rather annoying, considering you have no ties to their guild whatsoever.
To think that is acceptable would also mean you think that the Warriors should stop helping newbs, as you could make a profitable business off that IC. If you don't like a guild's IC stance against you, fight back IC, instead of resorting to buzzwords like harrassment and threats of /report.
It just makes you look like even worse corporate scum, when irl, you'd be fighting back the way the USA did, secretly funding things to hinder the One, and playing out how the Tyndale Trading Company would react IC.
In RP, just like RL, there are things that happen and things that are said that are out of your control. In RL, you don't have access to a /report or OOC system, so you have to man up and fight back using tact and intelligence, because its rather hard to godmod in RL.
Not trying to be overly critical, but you are in the wrong in my opinion Donari, and you're overstepping the boundaries.
