Guild Wars 2

It would be great if:
1) Reporting a letter as spam also deletes it automatically.
2) Reporting a player as a gold spammer also automatically puts his account on temporary (maybe 24-48 hours?) ignore.

First point I agree with, but it wont stop it from coming. The accounts they are using are only used for a limited time.
Second step, no matter if only one or more reports were required this measure is unreasonable, it would not be used for a good purpose.

I suggest that you implement the “report as a gold spammer” function and have 24/7 people working on solving these accounts, they are not only gold spammers, the accounts are probably hacked accounts, a subject you are already putting a lot of effort into.

I am seriously tired of seeing goldspam in /map chat.

This is actually a suggestion and should be in the Suggestions Forum: https://forum-en.gw2archive.eu/forum/support/bugs/Issues-with-the-trading-post-please-post-here-MERGED/page/25#post87469

At any rate, the /block function was working to ‘ignore’ these spammers in chat; however, that function seems to be buggy lately and may be associated with how many people a player can block. Hopefully, they’ll add a fix in sooner rather than later.
