I bought their VPS, ran for like 10 days. No issues with the quality. I have used their VPS for the same purpose in the past without any issues. Out of the blue they suspended my VPS. When I asked on the support chat they told me they have sent abuse complaints on my email and I need to reply to each and everyone of them. Now a new abuse complaint was logged for every 1 out of 100 links I built using GSA. Long story short, I don't have time to reply to their numerous abuse complaints. It will take me the whole fucking day. Long story short: Don't use Hostwinds for any of your SEO software. Not unless you are planning to use tons of private proxies. I paid for the whole month, only got 10 days worth of action. Obviously it violates their TOS in some way or the other, so I did not worry about creating a refund ticket or anything. Just stay away from hostwinds if you are thinking about running something like GSA SER on it.
