I don't accept invites from people with private profiles or very low level, 1 game on account
or 5 items in backpack. Stop also send me phising links, all dodgers will be reported to Valve.
I ignore also all invites from private acoounts, because 95% of them are belong to scammers.

Don't add me, if you only want to have me on your Friend List. I don't collect random people.
Don't add me, if you only want to ask how did I get such an awesome backpack.
Don't add me, only because you collect people with high Steam level.
Don't add me, if you want to ask me the prices of items. I'm not a spreadsheet.
Don't add me for random trades.
Don't send me invites to yours stupid, lame and noobish groups offering nothing.
Don't ask me for rep, I don't give +rep after each small trade.
Don't ask me: "How are you?" and other random questions like that. I don't have time for small talk.
Don't ask me for free items. If I ever give free items to someone, then this person is my friend.
Don't invite me to play with you. I play whenever I want and I don't need encouraging.
Don't disturb me when I play multiplayer games. I have no time for conversation.
Sorry for my bad English. I'm not an American or a Brit.
