Spammers will be spammers, as i wrote above, it is epic few mods (not sure how many now) against hundreds if not more spammers.
Epic “improving” (read getting more aggressive) handling spammers, will not help in long run, however it will make life of all “legal” users here more difficult.
Best example is DRM and anti piracy with games, as everybody knows games are pirated anyway, and pirated (cracked) games work better than protected with certain DRMs. Same would happen as result of fight against spammers.
ps.
Epic could make reporting spam easier, with less clicks and no extra login to another page.
