The random-number addition is sometimes suggested by websites as a simple way to retain personalization but bypass collisions with existing names. "behnamoh is taken. Would you like to use benamoh37?" Some people will tag on a birth year, address, or zip-code if their preferred name isn't available. You'll also see people sequentially add numbers to the end if they have forgotten a password or lost access. Lost your HN access, but still want people to know who you are? How about behnamoh2? Do it again? behnamoh3. I've seen family elders do this over and over with email addresses and Facebook accounts.
