So recently there has been an influx of spam bots on these forums, and a nifty feature I discovered SMF has built in is the ability to hide posts from these bots. Strangely though you don't do it from the poster you want to hide.
If you go to your own profile, then at the top select modify profile then follow the menu down to Buddies/Ignore List, then select edit ignore list. Conveniently as you type in names it automatically suggests the full name so you dont have to worry about any special characters in the name.
While this doesnt prevent spam topics showing up, it does let you read a thread more continuously without annoying chat-gpt generated content from russian toll farms, and makes it much easier to hold conversations.
