Am i climbing to fast?

I recently came back to league after getting a 14 day ban and taking a break to clear my head. Since I have come back I have gone from like gold 5 to gold 1 and am getting 25 lp a win. I just moved back to college and my ip is different than what it is at home so I worry riot will think im having the account boosted. I know I won't get season rewards because I doubt I can make it back to honor level 2 before end of season but I'd hate to lose my account for "getting gud". Should I be concerned at all? Thanks.
