Mateus? No. The entire game? Oh you bet I do. Except it's not so much a dog as it's a rabid wolf chalk full of rabies. You imply this is a Mateus problem. Excalibur is currently dealing with the same issues with house hoarders except two of them are botters and one of them is a confirmed gil seller. Despite showing evidence, video etc to S-E, nothing has been done to this person or the farm botter for that matter. Hyperion was also no different either and I was in that server since Beta. It only got bad when two or three groups decided they were housing barons and wanted to turn a profit on them.
This isn't just a Mateus problem. This is a game-wide problem.
Comparing mounts to plots is a really bad example. Mounts are an unlimited supply. Houses, not so much. You can at least farm mounts with proper groups and time even with low drop rates. You also don't need an alt to circumvent a limitation to getting a mount either, so again your point is a really bad comparison. There's also no drop rates on housing either.
Again, them "earning" those houses in a ward that's barely been up for a year is a stretch. They earned the cash for them. They chose to use that cash to make alts and buy plots with them. Sure, won't argue that tenacity but at some point this negative attention was bound to happen and if they expected no feedback from other Mateus players new and old then they're daft for it. Even more daft for having an interview with a known internet magazine and saying the things they did. As I said, it'll be a matter of time (a long time maybe) before an audit is done and S-E goes "Yeah... two subs owing 28 houses on a data center. That's gotta get fixed" - I'm hoping the extended delay of the Kugane plots from 2 weeks after launch to estimated time of 4.1 was hopefully for a strategy to be in place to deal with their own blunders and to not repeat the same mistake.
Anyone who also argues that you "don't NEED a house" can also suck a fat juicy lemon. It's a function placed for everybody to enjoy - you don't get to downplay others who want a house while defending those who have all the houses because they have fat stacks and unlimited free time on their hands.
