What you were up to, you mean. From the beginning you're personally attacking me and harassing me, and this is the only way you found to try to claim ownership of articles.
And yes, it's highly suspicious that you seem to monitor everything that happens between the IP and me. At worst, it shows that you're actually tracking down my edits, ie harassing me, at best, it proves you are the IP because without any communication with me or the IP, there is no way you can be aware of anything in so much details(unless you're harassing me). And no, that you happen to hear about this matter right after it occured, while nothing suggested you were active here for 2 days, cannot be coincidence.
And finally, please, Buspar, stop playing on words. This is what the admin that took in charge your SSP case stated, and nothing else: "Looking at contribs, User:Buspar and User:Xuanwu are very probably the same user. Technically, they cannot be socks, as one username was created after the other stopped editing". 
This statement is based on the technical definition of sockpuppetry, meaning that a person is using different identities at the same time. The admin only noted that the 2 accounts were not used simultaneously, but nonetheless acknowledged that Buspar and Xuanwu were the same person ("Looking at contribs, User:Buspar and User:Xuanwu are very probably the same user.")
The admin, however, never confirmed that you were not the IPs Onethirtyeightdot suspected you to be. If you've seen the line "No, Buspar is not 130.49.157.75", then please source it correctly.

So, what do we have ? An admin confirming you're likely to use several identities, an anonymous IP acting in exactly the same way as you do, having the same personal issues with me, editing the very same articles as you do, reverting back into articles the very same contribs that you made, and it also seems both you and the IP seem to have a telepathic link allowing to know every issue occuring with the IP without you being contacted by it beforehand.

As I've said, I'm offering to peacefully resolve this problem. 
I am sincerely convinced that Buspar is the IP, because I've noticed the very same edit pattern, because both users contribute to the same articles, and both users seem to have a personal issue against me and both seem to systematically revert my contributions as soon as they concern article about illegal downloading.
Thus, this is not randmon bad faithed accusation. This is only what I sincerely believe.

However, if it is absolutely proved that Buspar and the Ip are not the same and that Buspar and the IP don't behave in similar ways, then I'm ready to make excuses to both users and to stop identifying the Ip as Buspar. 

But if someone has any doubts about the IP identity, or if someone clearly acknowledge that Buspar and the Ip have the very same behavior and edit pattern, then that's all I need. I won't continue to call the IP Buspar, on the condition that an admin clearly acknowledges the IP¨as being Buspar, and that Buspar in his future edits, only revert edits of mine and talk to me under his Buspar username.
