That sort of behavior can alienate everybody else watching at best, and cause schizos to lose their minds and make up crazy rrats at worst (just look at how eternally butthurt some people on /vt/ get over mods in chat). Then there's the actual groomers who get aggressive over what they think are other groomers stepping in on their "territory".
For me it was never really about receiving something in return for the donation, not any more than the standard "thank you" that all donations get. I never felt like I somehow deserved something special for it or like there were strings attached
