So long as his affinity is lightning, then I have no problem with the Lightning Slayer. The Lightning Wolf, however, is still one o my favorite moves and I would prefer that you not use that one. You are free though to use any of the other derived techniques (shower, cascade, etc)
I am on right now too and I got your message on TBF. I am growing tired of it here as well; I left after you did. I put a blog up enlisting other users and if i don't get enough, then I am going to leave for good.
I don't think I've ever been blocked on BFF, but I don't go on that shitty site so who knows? XD It's be MAD AWKWARD if I was blocked though on BFF, awkward; why? Because I don't fucking go on it. XD But then again, I was blocked on Fairy Tail for because of CHAT ACTIVITIES! So not even because I made shitty articles or anything (as I never once edited on that site in terms of making fanons). They said I was trolling on chat because I was hating on Fairy Tail. Rofl, they're the ones that asked me my thoughts on it, I wasn't even going to bother and I said it in a polite manner. XD So, fuck it, I don't know. I could be blocked on BFF for all I know. XD
