Tail Note alternatives

Waalaxy is an amazing tool to automate prospecting on LinkedIn. It helped me to save a lot of time and energy. I went from 50 relations to 400 within a few weeks, I got multiple calls with potential clients. However, be careful : LinkedIn doesn't like this kind of automating tool at all. Compared to Facebook (which immediately blocks you), after 3 weeks of an intense use of Waalaxy, LinkedIn showed me a warning message saying that the number of profiles I was visiting was suspicious, and I had to check a box to certify I don't use any bot. From this moment I had to considerably slow down my use of this tool to not get blocked. Even though it helped me a lot to grow my LinkedIn profile, I wonder how this kind of tool can exist, it's against LinkedIn terms of use. Please use it with caution.
