I've shared my feedback with Keita on the changes separately - so I won't cover that, but I thought I would pitch in here to address some concerns I've seen some people post about, since I was the one to write the previous rules when Hawluchaa and I reworked them.
The reason for inconsistency between the two is that they are two very different environments. Ingame, staff cannot see DMs, it's a very fast paced environment in comparison to forums, and there is a lack of evidence control (players have to make screenshots, and they don't always include timestamps - it also may not be immediately clear which timezone that player is from, especially to other players). In addition to this, the forum clock only shows HH:MM and ingame shows HH:MM:SS.
To take your example of the rule about Instas, Min Raises and Accepted Payments - you cannot edit an ingame message like you can with a forum post, so if your auction begins immediately, the auctioneer will have immediately screwed themselves if they missed those details off, since they can't add them after. There's some other reasons too, but hopefully this is enough information to share with you why this would be this way.
This rule exists because of the sheer amount of auctions that ended, where the winning bidder wasn't available to make the trade. In those situations a TMOD will attempt to force the trade - that being said a TMOD can't be expected to magically know that you had the money on an alt on another server and to go and remove that from your account without speaking to you.
All that is asked is that you make sure the money is available, so if the trade does need to be forced, a TMOD is able to do so without delay (in addition to clearing you of potential false bidding, that's a whole other rabbit hole), and if it's not on that account, which account they need to look at. You stating the name of an alt account is also giving TMODs permission to take that money from another account too.
In relation to your suggestion - do you really think it's fair to make an auctioneer wait an extra 24hrs because it was inconvenient to you to make sure you had the means to pay?
If this is happening, you need to report it, otherwise staff won't be aware and there's not a lot they can do. In addition to this, staff won't announce each time they force a trade - it happens by default on the forum just because staff need to communicate to both players what's going on, but for ingame stuff it just won't happen, it'll all happen in the report center. This is why keeping evidence is really key, especially for ingame transactions/agreements - again, staff don't have access to PMs so they are hugely reliant on players coming forward with those cases.
Actually it does. It's innately unfair to change any aspect of an auction after it has started. As a general rule of thumb, auctions cannot be changed in any form once started unless explicitly stated by a TMOD. Happy to write an entire wall on why this is if you feel you need to know more, but as a whole keeping a flat simple ruling that auctions cannot be changed after they start makes auctions much simpler to handle, both as staff and as a player.
This topic was discussed at length and this is how General Trade Rule 1 came about. Realistically, trying to define community terms like "godly" "epic" etc is really difficult, who are staff to say what those things mean, let alone enforce based on them. Those are opinion-based words, and have nothing to do with anything quantifiable. What we put in place instead was a quantifiable system instead, there's no grey areas, no opinions - it either meets the criteria or it doesn't.
In regards to advertisements like "best in server", these aren't permitted and those advertisements should be amended. That's straight up false advertising unless you have a recent screenshot from Walross saying it is legitimately the best in the server.
In regards to your note on what Salem said, I responded to him above if you want to have a read.
Also +1 on the trade rules ingame. I think there's a character limit that might make it difficult but if it's possible, all for this.
