SENuke is over rated and heavily relies on automatic account creation on free sites, these web 2.0 sites are catching wind and finding ways to prevent automatic account creation. Even if you get all the links accounts working there really aren't that many of them. SENuke is nota long term solution for solid rankings, it might be ok for uncompetitive phrases but if you want to rank for something substantial you need something that builds a lot of permanent backlinks that you can rely on and in a larger quantity than SENUKE can provide.
I personally use Linxboss which costs a bit more than SENuke but has gotten great results over the past 7/8 months. Its not a piece of software , its a service that builds 1000 links a month from a private blog network, there is no work involved, you just put in your domains (up to 5) and your keywords and thats it, you get 200 links to each domain every month spaced out and built in a random fashion. So far I've been very happy with the results.
