I have a number of gmail accounts. I wanted to grab some username addresses for myself (not that I think 'beefalo.n.bunnyranch' was in danger, but it's mine darnit). With gmail you have to be invited to open an account so I invited my self over and over. I think I have a dozen accounts now. Oh, if you want gmail I have lots of invites - say about 50 per account...
There are 3 main accounts I use that have my name in them in one way or another and I forward all my mail to yet another account that I set up for my LiveJournal buddy's emails -- that reminds me, if you ever send me an email and shortly thereafter see something in your inbox from "ebil.librarian" that's me, I forgot to log out and reply from the account you actually mailed, so don't delete me as spam please.
Anyway -- have you noticed an influx of email purporting to be from eBay or PayPal about your account? Lordie. I have dozens of them. Now I do have a PayPal account and an eBay account. But the email address for them is not a gmail account, it's Yahoo, so I know all these are phony without even having to know something all technical about urls and headers and all that. I just forward them to the abuse team at gmail. Oh, btw, the spam filters and ph!shing warnings at gmail catch 98% of these so I'm very happy. I have to purposely go look at my spam folder to see this stuff. I go there every so often to make sure real email isn't accidently being sent there.
I truly enjoy how some of these emails start off "Dear Ebays" or "Dear PayPals". Sometimes the grammar and spelling is bad, other times it's pretty good. I can see how some of them could fool people.
Is spam a big problem for you? Comment spam was a problem in my other blog at ohdawno.org and I must have about 20 IPs blocked. For a while it was all about poker and online gambling, I think because I posted about my trip to Vegas.
OK, time to go, the SO has climbed into bed and covered his head with a pillow. I think it's his way of saying it's time for bed.
