社交网络问题

社交网络 itself is sufficient enough as a title. 社交网络问题 looks wordy. If you want to make it clear that you are going to discuss the negative sides of social networks, I would try 社交网络的缺点. 问题 sounds neutral, so it does not provide a lot more information.

我觉得脸书也许会增加社会问题。Adding 会 sounds more natural. 增加了社会问题also works if you want a past tense.

虽然脸书有很多优点， 但是缺点也许多。Usually we say 有许多/很多缺点(很多 is more often used)，but when it comes to 缺点也很多, we don't use 缺点也许多.

在欧美国家极右翼的看法越来越提高，有影响。 The far right is growing and having more influence. 极右翼（的势力）不断增强，影响力越来愈大。I want to know why you wrote 看法 in Mandarin, which did not exist in the English text. I just want to make sure I did not misinterpret it.看法越来越提高 is wrong. 看法有影响/越来越有影响works.

为什么？ 很多原因- 一部分是在经济危机，欧洲的领导不没有帮助普通人。不帮助 means they don't help, 没有帮助 implies they did not help. Remember the comma!

不过我也觉得，也许一部分是网络社会社交网络的责任。/As others corrected, 也许社交网络需要承担责任 also works. 网络社会means the internet community.

因为脸书推荐我们看同样看法的人的意见，所以我们不认识明白/了解对手的问题，和看法。1认识 usually goes with a person, e.g 我不认识你. But sometimes it goes with a object too, when used as a noun. 深入对这个问题的认识.. 明白/了解 works better when you want a verb to go with an object. 2. Now you don't need comma between very short parallel phrases.

并且可以会/可能增加误会。可以 is usually used to describe a person's ability, e.g. 我可以飞. If you want o describe probability, you need 可能. For certainty, you need 会.

现在我们跟我们的对手没有聊天，没有商量。跟我们的对手没有沟通(和)商榷/商量. 商榷 is a higher-register expression. 聊天 is chat.

我们只批评他们。 因此我们不可能了解他们。

并且，好像扎克伯格不是诚实人。不是一个诚实的人/不诚实. 

虽然他的责任很大，但是不想负责问题，解决问题。但是他不想承担责任并解决问题。/不想负责，不愿意解决问题.  不想负责并解决问题 sounds okay but I would choose 不想承担责任并解决问题( the reason is below).

负责问题 is wrong, as in other corrections, 对问题负责 is fine. 不想对问题负责、解决问题 sounds less natural than 不想承担责任并解决问题(the latter has parallel phrases, and a rhythm)
I think that Facebook maybe increases social problems. Although it has a lot of advantages it also has disadvantages. In Europe and America the far right is growing and having more influence. Why? There are many reasons. During the economic crisis European leaders didn’t help the ordinary people. But I also think social networks may also be responsible. Because Facebook suggests that we see opinions of people who agree with us we don’t know our opponents’ opinions or problems. Also, it increases misunderstandings. Now we don’t talk to or negotiate with our opponents. We just criticise them. Therefore, we don’t understand them. It seems that Zuckerberg isn’t and honest person. Although he has a lot of responsibility, he doesn’t want to take responsibility and solve the problem.

Thanks for the insight Ross!

我觉得脸书也许增加社会问题。虽然脸书有很多优点， 但是缺点也许多【“但是缺点也很多”or“但是也有许多缺点”】。在欧美国家极右翼的看法越来越提高【极右翼的声浪越来越高】，有影响【“越来越有影响”or“影响越来越大”】。为什么？ 很多原因- 一部分是在经济危机【在……中】欧洲的领导不帮助普通人。不过我也觉得也许一部分是网络社会的责任。因为脸书推荐我们看同样看法的人的意见，所以我们不认识对手的问题，看法。 并且可以增加误会。现在我们跟我们的对手没有聊天，没有商量。 我们只批评他们。 因此我们不可能了解他们。并且，好像扎克伯格不是诚实人。虽然他的责任很大，但是不想负责问题【对……负责】，【“并”or“和”】解决问题。

我觉得脸书也许會增加社会问题。虽然脸书有很多优点， 但是缺点也不少许多。在欧美国家极右翼的支持者日趨普遍，其影響力也日漸提升的看法越来越提高，有影响。为什么？ 很多原因- 一部分是在经济危机中，欧洲的领导不帮助平民普通人。不过我也觉得也许一部分是网络社会的责任。因为脸书推荐我们看同样看法的人的意见，所以我们聽不見反對者的聲音與不认识对手的问题，看法，。 并且還會可以增加误会。现在我们跟我们的对手没有對話聊天，没有交流商量。 我们只批评他们。 因此我们不可能了解他们。并且，好像扎克伯格似乎並不是诚实人。虽然他的责任很大，但是不想负责问题，解决问题。

社交网络 我觉得脸书也许增加社会问题可能会给我们增添许多社会问题。虽然脸书有很多优点， 但是缺点也有许多。在欧美国家，极右翼的看法越来越提高，有影响越来越多的极右派们变得更有影响力。为什么？ 这里有很多原因- 一部分是首先，在经济危机欧洲的领导不帮助普通人在经济危机下的欧洲，许多国家的领导人不愿意帮助普通人群。不过我也觉得也许一部分是网络社会的责任我觉得社交网络应该也有一定的责任。因为脸书推荐我们看的是那些有着和我们同样看法（相同观点better）的人的意见，所以我们不认识对手的问题看法。（ 所以我们不会知道对手们的观点和问题better）并且可以而且还会增加误会。现在如今我们不和我们的对手交流或商讨没有聊天，没有商量。 我们只会批评他们。 因此我们不可能会了解他们。并且，好像扎克伯格不是诚实人。扎克伯格似乎不是一个诚实的人，虽然（尽管better）他的责任很大，但是不想负责问题，解决问题。但是他并不想承担责任和解决问题 I think that Facebook maybe increases social problems.
