MMR Boosting Concern

I'm actually a little concerned here with all these threads about people claiming they weren't boosting and are now banned, I've progressed throughout the years on League starting from S2 Silver, S3 Gold, S4 Plat and now S5 Gold 3 and climbing from gold 5 0 lp.

I've played from multiple locations and I've recently moved, AND have been playing league a bit more than I used to now that other games have fizzled out and I find myself with more time on my hands.

Now my playstyle hasn't changed, I still play mainly the same champs, still have the same runes/runepages and still try to avoid the jungle at ALL costs, but I have been on a win streak, and I have picked up a new champ and have been reverting to some old ones (Anivia/Lux/Zyra) that I used to play all the time

Normally I wouldn't even worry about anything, but there's been alot of threads popping up of bans on innocent accounts and no Lyte hammer being dropped in there to solve everything.

So should I be concerned with the sudden surge in my attempt to get back to plat, or no?
