Is there a way to automatically block level-zero Steam profiles?

Solution 1:

Google chrome extension called "steam inventory helper" which can auto decline friend invites under certain levels, you can decide in the settings, I always have it set to auto decline levels 1 and under

Solution 2:

Not currently to my knowledge, instead of blocking them, just click ignore, this will prevent unread chat messages from building up, once you ignore a BOT that specific one should not bother you again. it is hassle to deal with them, but non the less, something may be done about this, due to the high demand for something like this.

Solution 3:

Sorry if this is a little late but.

I have a work around. Its not a way to auto-ignore bots but at least make it easier to block the users in a browser (blocking private accounts, unsetup accounts, users under a specific level) Hope it helps
