This thread was last updated a month ago, but this is serious shit. I have been told several of my gmail accounts have been locked over the past week. I just created a NEW gmail account, and while I was customizing the settings they locked me out. Literally, the account wasn't in existance for 10 minutes yet. No outgoing emails, no incoming emails. I have a total of 12 gmail accounts. Half have been locked. After 24 hours I can get back in, but then almost immediately they are locked again. Most of the gmail accounts are legit. Some are not ... they have been used for Craigslist activities. I've never created more than 1 gmail account a day. No gmail account has received more than 300 emails in a single day. No gmail account has sent more than 300 emails a day. The gmail accounts are locked regardless of the IP accessing it (home & work). All gmail accounts have been created via the same IP (home). Thank god I hadn't started using Gspace or Gdrive yet ... I was about to install the firefox extensions. Looks like I'm going to have to transfer my gmail accounts to another free service. Sucks all around. Hope this was helpful.
From my experience try to limit it to less than 200 emails per day. But besides what did you expect you're breaking gmail's tos by sending automated messages and stuff use proxies, vps servers ~MG
OMG wow that's freaky!! but they say it's only for 24 hours after that I suggest moving all the important info elsewhere
You may have spyware that causes your system to refresh. I had this a while back but Google never got on my case about it but I did have a few sites that had noticed it. Maybe reformat and change your account password to see if this helps. It doesn't sound like you are permanently blocked but it does sound like there is something going on with your account.
If your email is necessary to your business or whatever you need it for, why dont you just do what everybody else does and get reliable hosting using your own domain name? Jon
