If a person actually is interested in having real constructive discussions concerning Bitcoin or cryptocurrencies, he/she will pay the small fee. And if he/she can't afford the small fee, then there are other Bitcoin communities out there (e.g. Reddit/Twitter). It's not like they're totally shunned off out of Bitcoin if they can't get into Bitcointalk.
Two or three years ago I would have agreed with you but I don't feel like that anymore.
It makes no point to cast users aside when they are newbies and throw them to other social media websites that are full of shills and paid posters where usually newbies get the wrong idea about both bitcoin and crypto in general.
When I was browsing the forum created by yobit I was genuinely surprised by the number of people that were posting in a "vs bitcointalk" topic and were sure that bitcointalk requires a membership fee to use.
On the other hand, spammers are far less incentivized to continue their spamming spree if there's a fee. Yes, the fee is not that much, but it really adds up as they make more and more accounts.
I don't know...Maybe getting rid of the evil fee and instead of that putting a captcha on every action form made by a user who signed up via an evil IP? And maybe remove that once he gained 10 or x merits? Keeping spammers away while losing also a lot of users, maybe trying to deal with them would be better?
In this case, what works is that spammers or farmers of their accounts will feel completely free.
The forum is allowed to enter from any VPN or proxy. I may repeat myself, but what's the problem with buying a VPN? For 2 or 3 accounts, since you really need alternative accounts, you can spend a little.
Common, the average user that is just now looking for information about bitcoin will run into that and will not bother to install a VPN (if he even knows how to install one) but will simply close the window and go to a different place thinking that you need to pay to access this as you do with some newspapers that are behind a paywall. Not everyone is born with all that knowledge and learning is one thing this forum should be a part of in my opinion.
