Even you joined the forum with money-incentivized purpose, with time you can change yourself and become a good member of the forum. Everyone can change and if you can change yourself in a positive way, it's good for you and for forum community too. Because if you upgrade yourself to be a more knowledgeable and helpful member, the forum community will have more contributions from you.
An example is

His reason to join the forum and how he became one of good forum members, not only in merits.
The purpose of joining the forum may differ for now but the main reason when one have joined the forum cannot even be completed without having that knowledge about bitcoin. Even when you’re just focused more on ranking up and getting to be picked in a signature campaign, you must have learned a lot about the forum rules and also learnt about bitcoin. There is no way someone without the knowledge of bitcoin at least will survive to a full member rank in the forum. If there was a doubt for his knowledge and how he communicates in the forum, his ranking up will be hard and until he has improved, he won’t get that desirable rank for a campaign. So everything works in succession to me and at least, you may have something to show that you’ve passed through the forum like others.
