A number of fields, including philosophy, are organizing lists of signatories who will boycott the University of Illinois at Urbana-Champaign until the contract with Salaita is honored and the Chancellor reverses herself. I'm of two minds about this: on the one hand, the public threat to boycott the university might have some influence; on the other hand, it seems manifestly unfair to punish colleagues there who might want my contributions to a scholarly event, as they have in the past. (Many of these colleagues are as appalled as everyone else by the craven cowardice of the Chancellor in this matter.) Those colleagues, and their students, did not engage in any wrongdoing, yet the burden would fall on them for the Chancellor's misconduct if the signatories make good on the threat to boycott the university.
I'll open comments on this for arguments on either side of this question, but I want full names in the signature line and valid e-mail addresses (the latter will not appear).
