I think this is a good decision you take, if this is only detrimental to many parties and interfere with all the other participants, there is no problem for everything you want to improve on this issue ..
Good decision, yes, and this is the very first time,IMHO, we have a list of spammers published on BTT Altcoin ICO thread.
Although this is the first time the ICO project, to show the data of all participants that spammers in Altcoin, hopefully this can be the motivation for other projects to be more assertive in terms of building a good quality project ..
