Hi Andres, sad to know that you’ve not discovered few toxic links using SEMrush. How did you find those toxic links? Have you used any other tool to find them? Also you might want to get in touch with the SEMrush support team and let them know about this issue, so they’ll look into it. But if you still are not comfortable with it, you might want to give a try to Ahrefs for a month or two to really find out the best one among them. I’d suggest you give a try to Ahrefs for some time to see if it’s the right fit for you.

As of September 2014, YouTube's own keyword tool stopped working. It was moved over to Display Planner's AdWords video keyword suggestions. To use it, you need to have an Google Ads account. Just like the non-existent YouTube keyword tool, it was created to facilitate paid video and ads promotion. Which is why keywords that you will find there might not be closely related to the topic that you want to cover.
The Lost Links tab has the same interface as the New Links report does. For your own domain you might want to consider tracking your own links in something like Raven or Buzzstream but this tool does report dropped links down to the day. Combine that with their crawling preferences (better links = quicker attention) and you can spot drops of substance quickly.
