Call Support at 3am......ask them why your domains were locked/disabled for no apparent reason, get a run-around asking you to verify who you are 5 times. Verify yourself and then get some bullshit excuse that the account was marked as fraud or because they received a DMCA notice to take down your domain (DMCA was fake btw), meanwhile they redirected your domains to their homepage, taking away your valuable traffic and income.
No warning or notification about anything.
Thanks but no thanks, I moved from GoDaddy and I'm never going back.
A simple Google search will bring up a million more GoDaddy horror stories with no real reasons provided by GoDaddy.
In short....GoDaddy sucks.
Namecheap, Name.com, Internet.bs and Moniker have all proven to be better from personal experience.
