It is this that is tarnishing the name of the
Wikipedia and
driving away good editors.
Rui Correia.
When the going gets tough the tough get going. They don't throw their
hands up, vainly protest, then give up.
Possible conflict of interest is a legitimate concern; however, it is not
a simple straightforward matter. Particular editors with troublesome
editing patterns can have multiple motives, and sometimes are simply
editing in good faith.
You're welcome to hang in there and fully participate in both editing and
discussing possible conflict of interest, just as you are welcome to
handle nitro provided you follow the "rules." I assume you have not been
blocked yet.
