I have this website that I have been building backlinks to (slowly). Now a friend shared me his premium backlinksindexer.com account so i added all my non-indexed backlinks there. Result.. 2 weeks later and suddenly on my WMT dashboard there is 0 (no backlinks) at all for this website.. no crawl/sitemap errors nothing. I had like 300 indexed links in my dashboard due to now. Did the premium indexer got me sandboxed or what happened? PS. when i check mysite.com in google it shows up.. also for some of my keywords it also still shows up in results.
