First off, unless you are part of a brand new shard, as you near the top 20, you might want to look at the names of the players and see if there is some sort of arena shard chat to ask to join. That will help you learn players payouts and often even give you some feedback on your team. You can often find them in this section.
Second, if you are 10k+ power less than some of the people you are attacking - and are not part of the shard chat, expect to be attacked back, either by them or others. On many "older" shards there is a certain respect for players who respect other's payouts...an "honor among thieves" mentality. On the flipside, there is a sort of lack of respect for "new faces" - especially if they completely disregard payout times, or attack when it's not theirs.
Often you can find someone's payout time on SWGOH.gg (it's the time their info is updated) - so if it says "2 hours ago" go ahead and have fun. If says "23 hours ago" their payout is in an hour - beware.
Also, sending an "Ally Request" to someone with significantly higher power/better toons whom you've just beaten is often taken (for right or wrong) as an insult. Don't do this - unless you really want to make an enemy of someone who is stronger than you. Especially since the meta changes. A team that can win now, might have a rough time later.
Finally, take note of people's guilds. If you have a hard time reaching an individual player, you might be able to contact his/her guild.
Of course, feel free to disregard any and all of the above. But if you find yourself being locked out at your payout, or struggling to break into the top 20, don't say you don't know why - it probably has to do with at least some of the above.
