Amazing. I restrained myself and didn't call out your ignorance, since I tend to use rather complicated sentence construction. You failed to learn when hit with the clue-stick.
So hey, let's play...
The sentence read "I reported the infringements, the spamming, the users who have a variant of the name (e.g. foo2525 instead of foo): to the spam-handlers and to the variant-users." Let's dissect this.
The disingenuous would read this to mean I reported everyone to the spam-handlers *and* the variant-owners. That's totally unhelpful. So, perhaps there is another interpretation, after one is finished with your ad hominem nonsense: It can represent two different actions. Obviously, "variant-users" cannot refer to spammers -- that's just stupid. Then, it quite obviously indicates the resolution path for the variant-owners is *to* the variant-owners. The use of "respectively" would force the reader to cross-correlate the phrases, easing the process.
So, learn some bloody English, you puerile, self-indulgent, narcissistic, entitled moron. When they invent a "does not exceed a 6th grade reading level" tag, I'm sure you'll finally come into your own.
