Well, if you have another website that you're not using anymore... and it's niche/backlinks are relative to your new domain/website you can do a 301 redirect for all the backlinks pointing from your old domain to your new domain/website.
Its good to have 10000 back links but, get the back links naturally , don't buy it. Do On_page and Off Page for your website and make listed in some payment sites. Then you will get automatically.
I totally agree with wiseman. That is true, firstly you won't be ablt to get there and by chance you do that then Google will definitely consider your site as a spam!
People get to caught up in getting a ton of links a day. Scrapebox is a great tool for for harvesting good blogs to leave value on and also prospect for a guest post.
If you are throwing 10,000 links a day 99.9999% will be crap links , most likely you will get banned or sandboxed. I pretty sure Google will ban that spammy crap
Hey dude its not easy to get backlinks in just one day because its a step by step process to get backlinks from other sites. I think its impossible to get 10000 backlinks in one day and may be it count as a spam.
