COMELEC demands that any involvement of the bloggers and netizens as a whole in a political campaign must be disclosed, no matter if it is paid or not.

Comelec Resolution No. 9615 states in Section 1 under "Definitions", Item No. 4 and No.5:
4) ... Political advertising includes matters, not falling within the scope of personal opinion, that appear on any Internet website, including, but not limited to, social networks, blogging sites, and micro-blogging sites, in return for consideration, or otherwise capable of pecuniary estimation.
5) The terms “blog” and “collective blog” refer to websites on which an individual or group of users, respectively, record news, opinions, and information, in varying degrees of regularity. A “micro-blog” refers to a blogging format which allows users to exchange small elements of content – referred to variously as posts or status updates – such as short sentences, individual images, or links to video material uploaded to the Internet.
As you should be aware, there are restrictions in the ways you should be campaigning or advertising for a certain candidate. So aside from making sure that you execute your rights via online tools such as blogs and other social media tools the legal way, you should also take note of the times / dates that you are allowed to do so. Take a look at the table provided by the COMELEC via its website.
