The spokesperson also said that Corbyn should not be held accountable for the discourse. The group hosted people such as Max Blumenthal, a controversial speaker accused of anti-Semitism.
Among many posts, the screenshots show members of the group discussing whether they prefer the term "ZioNazi" to "JewNazi'. I am very very careful, it is a secret group".
On Thursday, Scottish Labour students from 11 universities and colleges, including Dundee University, backed permanent United Kingdom membership of the European single market and customs union, a position supported by at least 10 out of 73 local party groups.
Mr Corbyn said the party "doesn't tolerate" anti-Semitism "in any form" and he would have challenged any abusive posts if he had seen them.
And because the most active members of this Facebook group also tend to be the more anti-Semitic ones, their views set the tone for the group as a whole. In one thread, a member comments "I$3 am reading Mein Kampf [by Adolf Hitler] ... everybody should be forced to read it, especially Jews who have their own agenda as to why they were not liked", reported the Jewish Press.
The Campaign Against Anti-Semitism published screenshots of messages said to have been posted on the Palestine Live group.
"Obviously any anti-Semitic comment is wrong".

In the coming week, the duo will head to Kolkata to begin work on the story post interval, when the lovers elope. Janhvi was then shooting for Dhadak in India and couldn't be with her mom in her last moments.
It also supports the findings of Britain's largest-ever survey of anti-Jewish and anti-Israel attitudes, published previous year by CST and the Institute for Jewish Policy Research, which found that the more anti-Israel a person is, the more likely they are to also hold anti-Jewish attitudes.
"As a result of these allegations, we will be filing a disciplinary complaint to the Labour Party against Jeremy Corbyn, Clive Lewis, Sebastian Corbyn and Jack Bond, submitting that participation in such a Facebook group is "grossly detrimental" to the Party under Chapter 2, Clause I (8) of the Party's rule book, as well as breaching the Labour Party Social Media Policy agreed by the National Executive Committee in 2016, which requires that Party members report "hateful language" by other Labour Party members".
Mr Corbyn's spokesman said: 'Jeremy and the Labour Party are implacably opposed to all forms of anti-Semitism and will take whatever necessary action to stamp it out in the party. In social media all sorts of things are posted which often others participating aren't even aware of.
"It is repugnant if there are antisemitic posts - and I gather there are".
Palestine Live's content was first revealed in a 250-page dossier looking at the posts and profiles of members of the group, compiled by the businessman David Collier, who said his blog was dedicated to "researching antisemitism inside anti-Zionist activity".
"Led by Richard Leonard - who has already proven to be an excellent leader of Scottish Labour - we are making Labour's voice heard for a radically fairer society". One of Mr Corbyn's slogans is "standing up, not standing by", but in this case he has not stood up, but instead he actively joined in'.
