Seven directors of the Lincoln City Supporters' Trust Board have resigned with immediate effect.
In a joint statement on the trust's website, the seven members say they took the decision following "negative campaigning" and "intolerable pressure."
They are Lesley Barker, Andrew Blow, Elaine Elvidge, Neil Ferguson, Helen Jacobs, Fran Martin and Secretary Geoff Forbes.
The statement, which is dated Friday, June 6, reads: "All of us who serve on the Trust Board are volunteers. Some directors have felt under attack for several years.
"They have experienced personal attacks and been the subject of various allegations concerning their individual personal integrity.
"Confidential Information has been leaked (on social media sites) making it very difficult for the board to operate effectively.
"Trust board members do not defend themselves on these sites, as to do so would be in breach of the confidentiality agreement drawn up at the Trust’s inception. This agreement has been entered into by all members of the Trust board.
"Some directors have also been subjected to ongoing barrages of emails despite reasonable requests that this should cease."
The statement goes on to say that the 'unjustly maligned' trust has successfully raised £1,600 in addition to funds raised by the successful Gold Members section.
It concludes: "The Trust Directors resigning today are all volunteers who have the best interests of Lincoln City Football Club at heart.
"They all lead lives away from the club with their own personal pressures and challenges.
"It is in that context that this decision has been made today. It has not been made lightly.
"But enough is enough. Every one of them will continue to support their beloved Imps."
Lincoln City Supporters Trust Board is due to hold its annual meeting on June 30th.
