It boils down to one fact, depende sa payment structure ng campaign na sasalihan mo. If it pays in bitcoin then sa isang sulyap palang alam mo na if worthit ba o hindi.
If it is stake-based, depende sa kung gaano kalaki ang bounty pool allocation sa Article campaign na sasalihan mo.
When I run a few article campaigns before and even now, mostly nakikita ko pino-post nila mga articles/blog posts nila sa Steemit, Medium, Cryptocoin pravda or Newbium. Posts in those platforms to me is considered a blog post; But, when it's posted on an active website, lalo na pag cryptocurrency-related website, plus factor yun. Meron nga iba sa LinkedIn pinopost.
Depende na yan sa bounty manager if your work will be accepted or not.
Just make sure to always have these on your article:
1. Authenticity (bawal yung kinopya mo lang sa ibang tao, website, blogs or even google   )
2. Proper Authorship (always lagyan ng authorship, mas maigi if pati btc/eth address mo, ilagay mo, anti-copycats narin yan)
3. An article that describes the features of the project you're participating in (minsan kasi yung iba, maling project yung dinidescribe.   )

Here's one campaign you can join right now na may article campaign category: EOSex (Naka-escrow bounty pool 'nyan)
