Terrible site Terrible site, looking once and get overloeade with SPAM. Trying to unsubscribe .... unfortunately doesn't work. You get a message "unsubscribed succesfully" and within one hour new spam mails apear. USELESS REPLY RECEIVED TELLING. you can adjust your settings, of course did I do this but as already advised this doesnét work. THEREFORE remove me from ALL your Servers

They kept spamming me for years… They kept spamming me for years (luckily just my garbage account), until I finally lost it and sent them an email telling them to delete my account and all my information. No answer – but they did double down on their spam messages. At least one email in January EVERY DAY. No thanks. 1 star well deserved.

Watch out for this scam Watch out for this scam! $169 Australian dollars taken from my PayPal account today, I had the genuine impression that my "upgrade" was for the cost of $5, without agreeing to further deductions. Additionally the " mentions" of my work - all false! An organisation totally lacking in transparency and integrity. I've logged my complaint with them - no response, 12 hours later, considering legal action now.

Good service I will just give this company credit fir refunding my money within just couple days. And no, I'm not working at this company.

Thieving spivs These spivs withdrew €214,80 from my credit card account without my permission nor knowledge. I have never signed up to any of their services and only accessed their site to read scientific papers that they make available free. Some were interesting but over the years I've downloaded less than a dozen - all allegedly free. I am puzzled how they gained access to my credit card account. I am considering legal action.
