I think it is about time to start from the beginning and describe what these accounts actually are.
A couple years back a user named Unknown394 abused sockpuppets in an attempt to uprate their own submission. For most people the story ended there, however it in fact continued. The user also had multiple youtube channels which he pretended were unique people. On some of these channels, he stole other people's TAS content without permission. This is what Spike's tweets were referring to. Multiple legitimate users called him out on it, BUT there were also a series of accounts that were created at these dates for seemingly the sole purpose of calling Unknown out on this behavior. All but one was created on the same date: January 24th.
These accounts later seemed to follow Spike wherever he went, agreeing with him at key junctures and attacking users he was known to have problems with at the time. As messages from The8BitBeast indicated prior, he received a large number of dislikes from Australia but unfortunately one can set one's country of origin to whatever one pleases, so this is not a solid indicator. However I still find it very hard to believe Spikestuff is not involved considering the ties between him and the exact behaviors of the accounts.
Now while I cannot prove that Spikestuff is definitively behind the accounts, what I can prove is that Spikestuff talks way too much about stuff he shouldn't.
Spikestuff has an incredibly bad habit of leaking private or staff information. In fact he had leaked from Staff areas prior to me becoming staff in order to bash other staff members that he disliked or disagreed with

Multiple completely uninvolved users have reported to me Spikestuff talking to them about Bruno and his previous comments to Spike, something I would hope would be kept private and between staff. One of these users was told as recently as the 17th of this year.
Spikestuff has also previously mentioned an invite-only Pacman discord where he and others made fun of the events surrounding
#6128: itsPersonnal's GC SpongeBob SquarePants: Battle for Bikini Bottom "In-Game Codes" in 02:06.08.
Now while this may not seem directly related to the comments at first glance, the fact is that Spikestuff talks about TASVideos drama to so many people and makes a spectacle of it. Because he does this, it's easily possible for somebody else to have jumped in on whatever he was making fun of at the time and created one of the comments previously listed.
At the very least I cannot see Spike as a team player, as trustworthy, as an acceptable representative of TASVideos, and as someone I would want to work with at this time.
