On game-specific forums you could use this grouping as to see either all devs threads or its active users' one-post solutions/infos.

I still do consider creating multiple one-post threads as a spamming, instead of utilizing centralized threads (like announcements/updates/etc). And of course, I can rename it to a better description if provided, as long as it includes bot spams as well.

It is fine. I was just a bit shocked when I saw my favorite dev posts being marked as spam ... but since mrkgnao explained when it does mark sth. as spam I can understand it. It also says "possible" and not "actual".

That's good thinking, I like it! I'm pretty sure wishlist alerts disappear after the sale they're attached to is over, but I don't know about the rest.

Then it should be easy enough to implement.

But there is a small caveat: I believe, removing such alerts also effect unmarking forum replies, chat messages, etc.
Do such side effects satisfy you?

No, I suppose that is too far for me. It might work for someone else but I do use the forum replies when they come up. If you want to implement a blanket removal for anyone else who might want it, though, that's perfectly fine.

A request for a BE addition, if I may:
- option to hide the new "Explore our catalogue" banner at the bottom of the home page (which prevents one from just pressing "End" to reach the News section).

Why not to go further and just move/duplicate news section right to the top?

I'll add this to my to-do list.

Even better! Thanks!
