GMail: Blocking abusers by IP address?
August 15, 2014 2:08 PM   Subscribe

I'm working with someone (outside of the US) who is getting a series of harassing emails to her GMail account. The abuser is sending from a number of addresses, and is thus hard to identify or block by account. Is there a way to get GMail to block mail by IP address? Filters don't seem to do it, and I doubt reporting the abuse to Google will get a response. Other solutions would also be appreciated (yes, I am talking to her about potentially using other services). Thanks!

The trouble is that the abuser is likely not to remain at a permanent IP, but rather to attack from various fresh new IPs assigned all the time.

In a similar situation I found Gmail's capabilities not up to the task. I switched to Webfaction and used their procmail abilities to write a bunch of custom rules that blocked the harasser's domains, aliases and fixed business addresses. A server that supports procmail could also block by IP.

This kind of setup was also great because rather than sending mail to the Trash, it sent it to oblivion, so I never knew about it. It is no fun to click on the Gmail Trash only to see hate mail from 27 days ago.

Your colleague might try using Google's violation report form. If nothing else, it might start a conversation with an actual person at Google. Sad to say, though, my experience with Google has always been met with a sort of "It's not our problem" non-response.

Is the abuser sending emails with a bunch of phrases in common? If they're sending emails with strings that would be unlikely to appear in legitimate mail, it might be possible to make a filter - the "Has the words" option in the filter creation menu, combined with a distinctive phrase in quotation marks (to force it to search for the exact phrase) would work. Then they could send the messages directly to trash, spam, or a holding folder.

This may not be an option for everyone, but in case it is: She can ask a trusted friend to periodically go through her email before she reads it, and delete any abusive messages before she sees them. (This may be useful in combination with other steps; for example if automated filters are catching some but not all of the unwanted messages, or if she switches to a new address but wants to periodically check the old address for legitimate mail.)

I'm really really good at building filters (based on informal syntax pattern analysis). If all else fails, feel free to memail me, I'd be happy to help.

What about using one of those gate-keeper apps where the recipient has to approve your email address before you'll approve their email?

Is the user sending from other google addresses, or from one external domain?

I would get two new email addresses.

One, call it A, she keeps private, known only to herself and very trusted confidants.

The second, B, becomes her "new" email address, and she gives that to people not likely to give it to the abuser. The second forwards to the first.

Then in her current GMail, she sets up filters for all the contacts she doesn't want having either the very secure A or medium-secure B, and for words that are likely to be relevant to her and not likely to be abuse. That stuff all gets forwarded to A.

Then, if B somehow becomes known to the abuser, she turns off the forwarding and sets up another new shell account that points to A. Meanwhile she gets to keep all her archive and doesn't have to tell everyone again about a new address.

If A becomes known to the abuser, repeat it all again, with an even tighter circle around the new A.

(The simpler version of this is to get one new account, keep it only to confidants, and leave everyone else with the GMail address. She has to set up forwarding rules for everyone she knows, and periodically sweep that account to check the rules haven't missed anything)

Oh: some care needs to be taken about who she emails from the new address with, obviously.
