Combating spam with your Gmail ID

Gmail LOGO
Did you know that Gmail doesn’t recognize dots (.) as characters within a username ? This means th1nk.dj[at]gmail.com is the same as th1nkdj[at]gmail.com for Gmail servers. OK, Great .. Now how’s that useful for me ?

We signup for tons of services a day, right from that online news subscription to that no-so-trusted site which said it needed your email ID to send the download link you just requested. Hmm.. what to do ?

Well, for the not-so-trusted sites, just use an email alias with a pre positioned DOT. Adding FilterTake this example. I have to give my email ID [th1nk.dj[at]gmail.com] to blogdirectories.com. But I suspect them on giving the email IDs to 3rd party services. So, I give my email ID as th1nkd.j[at]gmail.com and I get the confirmation link.

Now, I goto Gmail > Settings > Filter and create a filter for all mails with TO: containing “th1nkd.j[at]gmail.com” to go to the trash OR apply a label. That way, I can find out which site gave out my email ID to the gazillion spammers out there.

    unfortunately this does not work to stop spam, nor does the +keyword trick mentioned in the comments… the reason it doesn’t work is simple – all the information a person needs to extract the true gmail address is available in these aliases you’re creating… it’s trivial to reverse the obfuscation – in fact it’s trivial for a program to reverse the obfuscation, and since the tricks are so well known and gmail is so popular it’s virtually guaranteed that the email harvesters have already automated this task…

    You can also try address+spam@gmail.com. Everything after the plus-sign is ignored, and you can use it to filter stuff too.

    @ Ganesh

    No dude ! Since gmail doesnt count the (.) , bot.hack, b.o.t.hack, bothack are all ACTUALLY “bothack”, which is unique. No one else can make that ID with (.) in b/w ..
    Rest assured !


  13. thinkdj says:

    Hmm .. yeah ! But then you'll have to log in and out of the accounts..

    nice nice! 😀 i should have chosen a good username before. so if i create gmailcom@gmail.com it could also be gmail.com@gmail.com? cool!

  15. Me says:

    Wouldn't it just be easier to make a second (FREE, thanks to Gmail) address such as djsjunkmail@gmail.com? Then you could use that as the address to put on websites, etc.

  16. Ganesh APP says:

    Now that is scary. What if someone had an id say bot.hack@gmail.com.

    He would be getting my emails too. Have you actually tried this out ?? I can understand the spam folder. But why dont you get two such ids and check it out?
