What's up with the scammers???

What should they do? Maybe some real level 1 account invites You. They can't be sure that every level 1 account is a scammer.

scammers r everywhere

maybe you're just popular.

what could they(scammers) doing with add you friends?

Yeah I got 6 myself the other day, thankfully it seems to have stopped, for now...

I have 269 blocked scammers and phishing bots ;3

not seen any since weeks, but i autodecline all private or lvl0-10 accounts.

Today two popped up with "my friend want to add you but he had an error, go to this fake link"

I have a private profile. The only time i change it to Public is for SG to update. Maybe to visible for friends if i'm trading and the other guy wants to check me out, but since i rarely trade, that doesnt happen often.

seems like non of you would accept my friend-request if i'd send you one :(

because every level 0-2 account is a scammer...

you think thats bad? i have a bigger problem. one of them bugged my steam chat. so now i cant see any notifications whenever new messages arrive

I decline all friend requests unless I know the person IRL or we have had a conversation that warrants added - If some one can't just use trade offers or make a simple comment on my post - then they have no reason to add me as a friend.
I block all private profiles or super low levels. And because I'm a bitter trader I block people who send outright stupid trade offers.

I just don't accept invites anymore, easier than dealing with these nuts :D

I actually kind of doubt that Valve cares too much, but the general rule applies:

• deny level 0 or 1 friend requests
• especially if they only own one game or if their account was made extremely recently
• double this if all their friends are moderately high level steam users or their profile is private or has no description
• people with descriptions might actually be legit users
• don't click strange links. this is a given.

All you need to do is leaving all popular steam groups that are associated with shooter games.

In the OPs case he is part of several TF2 groups and I am sure the number of scam attempts he receives will go down to less than one per month if he leaves them.
