Can I publish the same content ont triond and bukisa?

I don't know the policy of Bukisa, but if you have published a content through Triond then you can not republish it somewhere else. And also, previously published contents are not accepted by Triond. So, you can not publish the same content on both sites. Triond strictly follow their terms and conditions so I suggest you not to attempt anything like this on Triond. However, you may published your previously published content on Associated Content. So, if Bukisa allow republication then go for AC with your already published content.
